Temperature and humidity monitoring with Bluetooth sensors

Food, medicines and flowers have to stay within a temperature range, and more customers now ask for proof that they did. A small wireless sensor in the load space sends readings to the vehicle tracker over Bluetooth, so you get the temperature and the location together.

Wireless, with no cables to run

The Teltonika EYE Sensor is sealed, runs on its own battery and talks to the tracker over Bluetooth. Stick it inside the body and pair it with a Bluetooth-capable tracker. Nothing gets wired into the refrigeration unit and there's no cable to route through the body.

More than temperature

As well as temperature and humidity, the EYE Sensor reports movement and orientation. Add a magnet and it can tell you whether a door is open or shut. That's handy for security as well as cold chain.

Questions fleets ask

Does the EYE Sensor work on its own?

No. It broadcasts over Bluetooth, and it needs a compatible Teltonika tracker in range to pass the readings on to Fleetalyse.

How long does the EYE Sensor battery last?

Teltonika quotes more than four years on its default settings. In practice it depends on how often the sensor broadcasts and the temperature it's working in.
