Three detection inputs give a technician more context about an event than one input can. The GTSensor 4.0 combines passive infrared (PIR) motion detection, vibration and shock detection, and temperature logging in one small unit, so an alert can tell you whether something moved beneath the sensor or whether the station took a physical hit, such as a snap trap firing. That context is the practical advantage. It does not make the sensor infallible, and it does not replace the inspection that confirms what happened.
Quick answer: The GTSensor 4.0 uses PIR to register movement in the zone directly below the sensor, vibration and shock detection to register trap releases or heavy impacts on the station, and temperature logging for environmental context. A single-signal device can tell you that something happened. Knowing which input fired helps the technician judge what probably happened and how fast to respond. The physical check still confirms it.

What are the three detection inputs in the GTSensor 4.0?
The GTSensor 4.0 is the hardware at the core of the GTO platform that Rook Pest distributes in the U.S. At 60 x 64 x 22 mm and 57 g, it fits inside most compatible trap and bait station enclosures. Each of its three inputs answers a different question.
| Input | What it registers | What it helps the technician judge |
|---|---|---|
| Motion (PIR) | A change in infrared signature in the detection zone directly below the sensor | Something warm moved through the station, as in a run-through or monitor station |
| Vibration and shock | Physical impacts, most notably a snap trap release or a heavy knock on the station | The trap likely fired, or the station was struck and needs a look |
| Temperature | Environmental temperature, logged continuously | Context for reviewing activity patterns over time |
PIR works on the same principle as a security alarm, tuned for small mammals in confined, low-light spaces. Vibration covers the event PIR is not built to confirm, which is the moment a kill trap goes off.
Temperature is different. It describes the conditions around the station rather than the animal, and that helps when you are trying to explain why activity rose or fell at a point.
Where does a single-signal sensor fall short?
Many rodent sensors rely on one detection method, usually a break-beam or a simple motion trigger inside the trap housing. That is a reasonable start, and it beats walking a route with a flashlight. The weakness is structural. One signal can say that something happened, but it cannot say much about what.
Take two common setups. A motion-only sensor in a snap trap station reports movement, but it cannot separate a mouse that walked through from a trap that caught one. A trigger-only device reports a catch but sees nothing at a non-lethal station, where the whole point is to learn whether animals are passing through. Pairing motion with vibration covers both jobs in one device, with or without an active trap mechanism in the station.
How does detection type help with false alerts and missed activity?
False alerts are one of the fastest ways to lose a promising pilot. A technician who drives to a site twice in one week for nothing stops trusting the alert on their phone and goes back to checking every station on the printed route sheet. At that point the sensors are decoration.
GTO alerts are delivered by email with the sensor location, a timestamp, and the detection type, motion or vibration. In our view, that field is the most underused part of a connected monitoring alert. A vibration event at a snap trap near a dock tells a different story than a motion event at a monitor station in dry storage, and the response can reflect that difference.
Detection type has limits. No sensor can separate a rodent from every other cause: a forklift clipping a station is a heavy impact, and warm airflow near a door can affect a motion reading. Detection type narrows the question. It does not answer it.
The fix is to review odd events by location instead of dismissing them one at a time. Our post on false positives and false negatives in sensor data shows how.
Missed activity is the more expensive failure. PIR watches the zone below the sensor, so activity elsewhere in the room will not register at that point. No alerts does not mean no rodents, which is why physical inspection stays in the program.
How do placement and station type shape what the sensor reports?
The GTSensor 4.0 can be used with snap traps, run-through bait stations, rodenticide bait stations, and monitor bait stations, with or without an active trap mechanism. Which input matters most depends on what is in the box.
- Snap trap stations: vibration is the headline input, because it registers the trap release. Motion shows whether there was traffic before the catch.
- Run-through and monitor stations: motion carries most of the weight. These stations exist to show traffic.
- Rodenticide bait stations: motion shows visits between services, useful when deciding whether a station needs attention before the next check.
- Busy aisles and docks: expect more impact events from carts, pallets, and cleaning crews, and read those alerts with that in mind.
Rodent pressure tends to concentrate in mechanical rooms, loading docks, cold storage, and voids. Those spaces are also hard on equipment, with temperature swings, dust, and machinery shaking the floor. Our look at how GTO hardware holds up in field conditions covers the environment side.
Test before you leave the site. Each sensor has an indicator LED that shows operational status. Passing a hand beneath the sensor or tapping the station confirms that motion and vibration detection are working at that point. Configuration lives on the GTO platform, not the device, so settings can be adjusted remotely afterward.
What does three-way detection mean for the account?
For the pest management company, the payoff is better information for the next service decision. A technician who knows the detection type, time, and location can decide how quickly to investigate and where to look first. Over weeks, the event history and temperature record can help explain recurring hotspots.
For the facility, it means a clearer record. Event history tied to technician findings and corrective-action notes shows what occurred and how the team responded. That can support customer and audit review, though it does not certify compliance on its own.
None of it works without a response process. Before deployment, decide who reviews alerts, who owns the ones that arrive at 2 a.m. on a Sunday, and how each one closes with a note. Our guide to building a technician response protocol walks through that setup.
Frequently asked questions
What does PIR mean on a rodent sensor?
PIR stands for passive infrared. The sensor registers a change in infrared signature, which is how it picks up a warm-bodied animal moving through the zone directly below it.
Can the GTSensor 4.0 tell a catch from a rodent passing through?
It reports which input fired. Alerts include the detection type, motion or vibration, and vibration and shock detection registers snap trap releases. That points toward the likely event. A heavy knock on the station can also register, so the physical check confirms it.
Does temperature sensing trigger rodent alerts?
Rook Pest’s product description lists motion or vibration as the detection type in alerts. Temperature is logged continuously as environmental context. It supports pattern analysis and reporting rather than serving as a rodent signal on its own.
How do you check that a sensor is detecting after installation?
Check the indicator LED, then pass a hand beneath the sensor and tap the station to confirm motion and vibration detection. Do it at every point before you leave. Coverage to the gateway should be tested at the same time.
If you are deciding where multi-input detection would help your team, start with a handful of stations where the answer matters most. Talk with Rook Pest about a monitoring pilot and we can help you choose the points, test coverage, and set up the response process.
