How Does a Moisture Sensor Work?

Answer

The moisture sensor works when the series of discs in the sensor expands they get wet, and to a certain size, they flip a micro switch, this interrupts the current going from the controller to the valves, whereby the controller will tell the valves to start watering in the middle of a rainstorm, if the valves do not get the memo then they don't turn on. When the discs dries out in the sun and the wind, then the switch flips back, and the valves will water when the controller tells them to start watering.
