DESCRIPTION
A rain sensor module is an easy tool for rain detection. It can be used as a switch when a raindrop falls through the raining board or for measuring rainfall intensity. The module features, a rain board and a control board that is separate for more convenience, power indicator LED and an adjustable sensitivity through a potentiometer. The analog output is used in the detection of drops in the amount of rainfall. Connected to a 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.
Pin Configuration
1. VCC: 5V DC
2. GND: ground
3. DO: high/low output
4. AO: analog output
