Raindrop Sensor Module | Rain & Water Detector for Arduino
Build your own weather station. This sensor detects rain, snow, or water droplets. It consists of a large nickel-plated sensing board and a control module. When water hits the board, it sends a signal to your Arduino to close windows or sound an alarm.
-
Sensor Type: Resistive (Nickel-Plated Board).
-
Outputs: Digital (High/Low) and Analog (Rain Intensity).
-
Durability: Treated against oxidation for longer life.
-
Best For: Automatic Wipers, Smart Clotheslines, and Weather Stations.
