Page 3: Introduction
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. -
Page 5: Data Report
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. - Page 6 ActiveThreshold InActiveThreshold Reserved SetActiveThresholdReq 0x03 (2Bytes) (2Bytes) (5Bytes,Fixed 0x00) Status Reserved SetActiveThresholdRsp 0x83 (0x00_success) (8Bytes,Fixed 0x00) R718E 0x1C Reserved GetActiveThresholdReq 0x04 (9Bytes,Fixed 0x00) ActiveThreshold InActiveThreshold Reserved GetActiveThresholdRsp 0x84 (2Bytes) (2Bytes) (5Bytes,Fixed 0x00) Assuming that the Active Threshold is set to 10m/s , the value to be set is 10/9.8/0.0625=16.32,and the last value obtained is an integer and is...

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.
