L02S Condition Monitoring Sensor

The L02S condition monitoring sensor, based on Bluetooth Low Energy technology, is an all-in-one sensor that contains a temperature sensor, hall effect sensor, and accelerometer sensor. It can monitor the door status and temperatures of the vehicle or trailer and broadcast the data via BLE to be picked up by trackers or BLE gateways and transmitted to the server eventually.

It can also locally store 50,000 groups of sensor data, which caters to the industry’s needs for continuous monitoring of cargo conditions in transit or not. Especially for companies that want to prevent losses from unallowable temperature deviation and unauthorized opening.

L02S monitoring temperature, humidity, door status

All-in-one sensing and monitoring

Multiple sensors are integrated into one device. You can monitor key metrics like temperature, humidity, door status, motion, and more without extra hardware. Keep your cargo safe and your operations running smoothly with the all-in-one L02S sensor. Integrated sensors include:
·Temperature and Humidity sensor
·Hall effect sensor
·Accelerometer sensor
·Barometric pressure sensor

Rotating replaceable battery design

Quick and easy battery swaps without removing the entire sensor from its mounted position. Just rotate off the bottom cover to access the battery compartment. Even after 3M pasting, it does not need to remove the entire product to replace and reinstall.
