Detect the rough driving of the vehicle: with its embedded 3-axis accelerometer, the device can detect the collision of the vehicle, harsh braking and harsh acceleration etc.

Monitor temperature: by connecting with temperature sensors, the device can detect and monitor temperature of freezer, give warning if temperature is too low or too high.

Monitor humidity: by connecting with humidity sensors, the device can detect and monitor humidity of freezers, give warning if humidity value is too high or too low.
