1. Introduction The R718E is identified as a LoRaWAN ClassA device with three-axis acceleration , temperature and compatible with LoRaWAN protocol. When the device moves or vibrates over threshold value, it immediately reports the temperature ,acceleration and velocity of the X, Y, and Z axes.
Low power consumption and long battery life Note: Battery life is determined by the sensor reporting frequency and other variables, please refer to http://www.netvox.com.tw/electric/electric_calc.html On this website, users can find battery life time for varied models at different configurations. 4. Set up Instruction On/Off Insert batteries.
5.1 R718E to report three-axis acceleration and velocity R718E will report immediately when it detects vibration that exceeds the Active Threshold. The next detection/report will not be ready until the the vibration has been stopped for at least 5 seconds. If vibration happens during this 5-second period, the period will restart.

The 0g offset or offset is an important accelerometer indicator because it defines the baseline used to measure acceleration. After installing R718E, turn on the device and wait for the device join the network 1 minute, the device will automatically offset the calibration.
