    Description
    Need to detect rain fall and keep your cloth in? You can use this low rain detector/sensor. It comes in 2 parts, the sensor plate and sensor module board. Not to forget the female to female jumper wires for you to connect the plate and module, also to your microcontroller.

    The sensor plate has 2 PCB tracks which routed parallelly surrounding it. These tracks are not connected, but when water/rain drop to the surface of plate and changes the resistance between the tracks because water/rain is conductive, this further changes the resistance between tracks and lower down the resistance. More water/rain touches the plate, resistance become lower. Using simple resistor network and voltage divider, you will get analog voltage output.
     
    The module comes with a comparator and adjustable potentiometer for user to adjust the threshold to toggle digital output. You can choose to use the digital or analog output.
