Page 3: Introduction
R718EB is the Class A device based on the LoRaWAN protocol of Netvox. The device detects the tilt angle of three axes. When the device moves or vibrates beyond the set threshold value, and after the device is stationary, if the angle variation of any one of the three axes is greater or equal to than the AngleChange, it will immediately report the current tilt angle of the X, Y, and Z axes and the battery voltage. -
