Rain Sensor Module is a simple yet effective sensor used to detect the presence of rain or moisture on surfaces. It operates by measuring the amount of water that falls on the sensor’s surface, which affects its electrical resistance.
Specification
- Voltage Supply: Typically operates at 5V or 3.3V (DC).
- Output Type: Analog or digital output (depending on the module).
- Working Temperature: Generally from -40°C to 85°C, suitable for outdoor use.
- Size: Small, with a board typically measuring around 3-5 cm on each side.
