Module function description

1) In water meter mode, when battery voltage goes under 3.2V the system will prohibit valve opening operation and periodic data uploading function. When battery voltage goes over 3.2V, the buzzer will beep and the system will return normal.

2) The module reads the battery voltage once every 24 hours.

3) Magnetic interference valve closing function. When a double reed switches meter encounters magnetic interference, the system will close the valve immediately. After disappearance of magnetic interference, the valve will remain closed for a specific period of time (according to configuration) and then be opened.
