Raindrops Detection Sensor Module Snow RainWeather (analog/digital)

The Raindrops Detection Sensor Module detects rain, snow and water drops with a sensing plate connected to a small comparator control board. It gives an analog output that follows how wet the plate is and a digital output that switches at a threshold you set with the onboard potentiometer, so an Arduino, ESP32 or ESP8266 can react to rain and changes in the weather.

Raindrops Detection Sensor Module Specifications

• Sensing: plate with interleaved conductive tracks
• Comparator: LM393 on the control board
• Outputs: analog (AO) and digital (DO)
• Threshold: adjustable with the onboard potentiometer (digital output)
• Supply voltage: 3.3 V to 5 V

Raindrops Detection Sensor Module Applications

• Rain alarms and home weather stations
• Automatic window, awning or roof closing projects
• Smart irrigation that pauses watering when it rains
• Car wiper and smart home models in STEM classes

What's in the Box

• 1 × rain sensing plate
• 1 × LM393 comparator control board

Tip: The sensing plate corrodes faster when it is powered all the time, so power the module from a digital pin and switch it on only when you take a reading. Mount the plate at a slight angle so water runs off and the sensor dries after the rain stops.
