Description
- Description:
The rain sensor module is an easy tool for rain detection.It can be used as aswitch when raindrop falls through the raining board and also for measuring rainfallintensity.The module features, a rainboard and the control board that is separate formore convenience, power indicator LED and an adjustable sensitivity though apotentiometer.The analog output is used in detection of drops in the amount of rainfall.Connected to 5V power supply, the LED will turn on when induction board has no raindrop, and DO output is high. When dropping a little amount water, DO output is low, the switch indicator will turn on. Brush off the water droplets, and when restored to the initial
state, outputs high level.
switch indicator will turn on. Brush off the water droplets, and when restored to the initialstate, outputs high level.
