Why Pest Professionals Choose the GTSensor 4.0
More Than a Sensor. A Complete Early Warning System.
Know the Moment It Happens
The GTSensor sends an instant email alert the moment rodent activity is detected — whether that’s a rodent passing through a bait station or a snap trap firing at 2am on a Sunday. Your team responds to a real event, not a scheduled calendar date.
Never Miss a Catch Again
With conventional monitoring, a triggered trap might go unserviced for days or even weeks between visits. The GTSensor eliminates that window entirely — every activation is logged and reported in real time, so nothing is left to chance.
Permanent, Continuous Coverage
The GTSensor doesn’t clock off between visits. It monitors 24 hours a day, 7 days a week, 365 days a year — providing continuous coverage that a periodic inspection schedule simply cannot match.
Data Your Clients Can Act On
Every activation is timestamped and mapped, generating a clear picture of rodent activity patterns over time. This data supports faster root cause analysis, smarter station placement, and the kind of audit-ready documentation that food manufacturers, hospitals, and airports require.
Works With What You Already Have
The GTSensor is designed to integrate with the traps and bait stations your team already deploys — from Bell Laboratories snap traps to Rotech bait boxes, Camro Safeboxes, and many more. No ripping out existing equipment. No learning new protocols.
Grow Your Recurring Revenue
For pest management professionals, the GTSensor unlocks a fundamentally more profitable service model — long-term monitoring contracts that generate reliable monthly revenue, reduce unnecessary site visits, and deepen client relationships.
Built to Perform in the Real World
Every Feature Engineered for Professional Pest Management
Feature 1
Triple-Mode Detection
The GTSensor 4.0 uses three independent detection mechanisms:
- Motion Detection (PIR) — detects rodents passing through the monitored zone below the sensor
- Vibration/Shock Detection — registers snap trap releases or heavy impacts on the station
- Temperature Monitoring — provides environmental data to support analysis and reporting
Together, these three inputs give a more complete and reliable picture of what’s happening at each monitoring point than motion-only systems can provide.
Feature 2
LoRa Long-Range Wireless Technology
The GTSensor communicates using LoRa (Long Range) radio technology at 915 MHz — a protocol specifically designed for IoT devices that need to transmit over distance with minimal power consumption. This means:
- Strong signal penetration through walls, floors, and building structure
- Low energy use, enabling the industry-leading battery life
- Reliable performance in large, complex facilities such as warehouses, food plants, and airport terminals
- No dependence on Wi-Fi or Bluetooth, which are subject to interference and coverage limitations
Feature 3
Up to 9-Year Exchangeable Battery
Powered by a standard AA 3.6V Lithium (LI-SOCI2) battery, the GTSensor 4.0 is designed for minimal maintenance. Battery life of up to nine years under typical operating conditions means far less technician time spent on sensor upkeep. And when replacement is eventually needed, it’s a simple, tool-free swap.
Note: Actual battery life varies depending on activity levels, ambient temperature, and signal conditions.
Feature 4
Internal PCB Antenna
The GTSensor’s antenna is built directly into the circuit board — eliminating the external antenna found on older systems. This keeps the device compact, lowers the risk of physical damage in the field, and maintains a clean, unobtrusive profile inside trap and bait station enclosures.
Feature 5
IP51-Rated Enclosure
Housed in a durable PC/ABS plastic enclosure with an IP51 rating, the GTSensor is built to withstand the conditions found in real commercial environments — including dust, moisture, and temperature extremes from -20°C to +85°C. It is suitable for both indoor and outdoor deployment.
Feature 6
Server-Based Configuration
All sensor configuration is handled through the GTO cloud platform — no physical reconfiguration required in the field. Settings can be adjusted remotely, and firmware updates are applied centrally, ensuring every sensor in a deployment stays current without requiring a site visit.
Feature 7
Universal Trap & Station Compatibility
The GTSensor 4.0 is designed to mount on or inside virtually any commercially available trap or bait station. It is not tied to a proprietary enclosure, giving pest control professionals the freedom to use the trapping hardware they already know and trust.
In Depth
The GTSensor 4.0 — A Closer Look
The GTSensor 4.0 represents the fourth generation of GreenTrapOnline’s field-proven wireless sensor technology — refined over nearly two decades of deployment in some of Europe’s most demanding pest control environments. It is a small device with a significant purpose: to make rodent monitoring continuous, immediate, and actionable.
How It’s Built The sensor unit measures just 60 x 64 x 22mm and weighs 57 grams — compact enough to fit discreetly inside most standard trap and bait station enclosures without affecting the station’s function or the rodent’s willingness to enter. The enclosure is manufactured from PC/ABS plastic, rated IP51 for protection against dust ingress and limited moisture. An internal PCB antenna handles wireless communication, removing the need for an external aerial and keeping the profile clean.
How It Detects The GTSensor 4.0 employs passive infrared (PIR) technology for motion detection — the same underlying principle used in security alarm systems, but optimised for the detection of small mammals in confined, low-light environments. When a rodent passes through the detection zone directly below the sensor, the change in infrared signature is registered and an alarm signal is generated.
In parallel, the vibration and shock detection capability monitors for physical impacts — most notably the release of a snap trap. This dual-mode approach means the sensor captures both rodent movement through non-lethal stations and confirmed catches in kill traps, providing a complete view of activity at each monitoring point.
Temperature data is also logged continuously, providing contextual environmental information that can support pattern analysis and help explain fluctuations in rodent activity.
How It Communicates All data is transmitted wirelessly via LoRa (Long Range) radio at 915 MHz — a protocol purpose-built for low-power, long-range IoT communication. Signals travel from the GTSensor to a nearby GTConnect gateway, which then routes data to the GreenTrapOnline cloud platform via a 4G cellular connection. The entire transmission chain is encrypted and hosted on Microsoft Azure infrastructure, providing enterprise-grade data security.
The LoRa protocol is particularly well-suited to large commercial facilities. Unlike Wi-Fi — which requires dense coverage infrastructure and is vulnerable to interference — LoRa signals penetrate walls, floors, and structural elements reliably, making it an effective communication layer in warehouses, hospitals, food plants, and multi-story facilities.
How It’s Powered The sensor runs on a single AA-size 3.6V Lithium battery (LI-SOCI2), with a rated battery life of up to nine years depending on activity frequency, ambient temperature, and signal conditions. LoRa’s low power consumption profile is the primary reason for this exceptional longevity — the sensor transmits only when needed, spending the vast majority of its time in a low-draw standby state. When the battery eventually needs replacing, it is a straightforward field swap requiring no tools and no reconfiguration.
What It Integrates With The GTSensor 4.0 is hardware-agnostic by design. It has been tested and confirmed compatible with a wide range of industry-standard traps and bait stations, including products from Bell Laboratories, Kness Pest Defence, Rotech, Camro, Plastdiversity, Lodi Group, Orma, Killgerm, Telex Pest Control, and Genicco. It can be used with snap traps, run-through bait stations, rodenticide bait stations, and monitor bait stations — with or without an active trap mechanism, depending on the monitoring strategy employed.
Setup & Deployment
From Unboxing to Online in Minutes
The GTSensor 4.0 is designed for pest control professionals — which means it needs to be fast to deploy, simple to operate, and reliable in the field. Here’s how a typical installation looks
1
Plan Your Deployment
Before installation, work with your Rook account manager to determine the number of sensors needed for the site, optimal placement locations, and gateway positioning. For most commercial sites, a single GTConnect gateway can support the full sensor network. Larger or more complex sites may require multiple gateway units.
Consider: High-traffic rodent run areas, entry points, known activity zones, and any locations that are difficult or hazardous to inspect physically.
2
Install the GTConnect Gateway
The GTConnect gateway is the communications hub of the system. It requires a standard power outlet and connects to the internet via 4G cellular network — no hardwired ethernet or Wi-Fi connection is needed in most cases. Position the gateway centrally relative to your sensor deployment to maximise signal coverage.
Installation is completed by the pest control professional. No third-party technician or IT support is required.
3
Mount the GTSensors
The GTSensor mounts inside or on top of your chosen trap or bait station. The device is held in position by the station’s internal geometry or via the integrated mounting tab. No adhesives, brackets, or tools are required for standard installations.
Once physically positioned, each sensor is registered to the site through the GTO cloud platform — a quick process completed via the server interface.
4
Activate and Verify
Once registered, sensors begin monitoring immediately. Each GTSensor has an indicator LED that confirms its operational status. A brief test — passing your hand beneath the sensor or tapping the station — will confirm motion and vibration detection are functioning correctly before you leave the site.
5
Configure Alerts
Through the GTO platform, set up your alert recipients — the pest manager, site supervisor, facility manager, or any combination of stakeholders. Alerts are delivered by email and include the sensor location, timestamp, and detection type. The platform also supports scheduled activity reports and dashboard access for clients who want ongoing visibility.
6
Monitor, Respond, Report
From this point, the system works autonomously. When an alert is received, the relevant team member responds to the specific sensor location — rather than conducting a full site inspection. Activity data accumulates in the dashboard, providing trend analysis that informs station placement adjustments and service scheduling over time.
Once physically positioned, each sensor is registered to the site through the GTO cloud platform — a quick process completed via the server interface.
The Full System
One Sensor. One Gateway. Total Site Visibility
The GTSensor 4.0 doesn’t operate in isolation — it’s part of a complete, integrated monitoring ecosystem. Here’s how the components work together to deliver real-time rodent intelligence
Component 1
GTSensor 4.0 The Detection Layer
Deployed inside or alongside traps and bait stations throughout the monitored site. Each sensor continuously monitors for motion, vibration, and temperature. When activity is detected, it generates a wireless transmission within seconds.
Multiple sensors can be deployed across a single site — there is no practical upper limit to the number of sensors a system can support, making it fully scalable from a small retail unit to a multi-building food manufacturing campus.
Component 2
GTConnect Gateway The Communications Layer
The GTConnect gateway receives wireless signals from all GTSensor units within range and routes the data to the GTO cloud platform via 4G cellular connection. A single gateway can serve an entire sensor network on most standard commercial sites.
The gateway connects over the 4G network — no Wi-Fi dependency, no IT infrastructure requirements, and no need to involve a client’s internal network team.
Component 3
GTO Cloud Platform The Intelligence Layer
All sensor data flows into the GTO cloud platform — a secure, multi-user dashboard hosted on Microsoft Azure. From here, pest managers and their clients can:
- View real-time sensor status across all locations
- Receive and manage activity alerts
- Access historical activity logs and trend data
- Generate compliance and audit reports
- Manage multiple sites from a single login
- Configure alert recipients and notification preferences
The platform is accessible from any device with a browser — desktop, tablet, or smartphone — giving pest professionals and facility managers full visibility from anywhere.
Frequently Asked Questions
Everything You Need to Know
Who is the GTSensor 4.0 designed for?
The GTSensor 4.0 is designed for professional pest management companies (PMPs) who want to offer their clients a continuous, real-time monitoring service. It is not a consumer product. Rook works directly with pest control professionals, who then deploy and manage the system for their clients. Facility managers and end clients can also contact us to be connected with a Rook-certified pest professional in their area.
Does the GTSensor replace my existing traps and bait stations?
No — and that’s one of its key strengths. The GTSensor is designed to integrate with the traps and bait stations you already use. It adds a digital monitoring and alerting layer to your existing hardware, rather than requiring you to replace it. It is compatible with a wide range of industry-standard snap traps, run-through stations, and bait stations from leading manufacturers.
What happens when a rodent is detected?
The GTSensor transmits a wireless signal to the GTConnect gateway, which forwards the alert data to the GTO cloud platform. An email notification is sent immediately to the designated recipients — typically the pest manager, and optionally the facility manager or site contact — including the sensor location, detection type (motion or vibration), and timestamp. The pest professional can then respond directly to that specific location.
How long does the battery last?
The GTSensor 4.0 is rated for up to nine years of battery life under typical operating conditions. Actual battery life depends on the frequency of detections, ambient temperature, and signal distance to the gateway. When the battery does need replacing, it uses a standard AA-size 3.6V Lithium cell — a simple, tool-free swap.
Does the system require Wi-Fi or the client's internet network?
No. The GTSensor communicates with the GTConnect gateway via LoRa radio — a dedicated wireless protocol that does not use Wi-Fi or Bluetooth. The gateway connects to the internet independently via 4G cellular network. This means there is no need to access or burden the client’s IT infrastructure, and site details remain completely private between the pest manager and their client.
How many sensors can one gateway support?
A single GTConnect gateway can support a large number of sensors — sufficient for most standard commercial deployments. For very large or complex sites, such as major food manufacturing facilities or airport terminals, multiple gateways can be deployed to ensure full coverage. Your Rook account manager will advise on the right configuration for your specific site.
Can sensors be used outdoors?
Yes. The GTSensor 4.0 has an IP51-rated enclosure and an operating temperature range of -20°C to +85°C, making it suitable for outdoor deployment in most commercial environments. It can be used in external bait stations, perimeter monitoring, and other outdoor applications.
