The accelerometer is a mechanical structure that contains components that can move freely. These moving parts are very sensitive to
mechanical stress, far beyond solid-state electronics. The 0g offset or offset is an important accelerometer indicator because it defines the
baseline used to measure acceleration. After the device is installed, it will be turned on. After 1 minute of network access, the device will
automatically offset the calibration. If the device installation position moves, you need to power off the device after a complete power off for
one minute.
Data report configuration and sending period are as following:
