Features

• Detects raindrops and water presence
• Large sensing pad: 54mm x 40mm
• Analog (A0) and Digital (D0) output
• Adjustable sensitivity via potentiometer
• Includes control board and sensing pad
• Comes with 2 jumper wires
• LED indicators for power and output
• Operating voltage: 3.3V to 5V
• Corrosion-resistant nickel-plated surface
• Ideal for automated irrigation and car wipers
• The Rain Detection Sensor Module is a versatile sensor that detects the presence of water or raindrops on its sensing pad. It consists of a large 54x40mm nickel-plated pad and a control board with analog and digital output.
• When water bridges the printed lines on the pad, resistance changes, producing an analog signal (A0) proportional to water amount. The digital output (D0) goes HIGH when water exceeds the set threshold (adjustable via potentiometer).
• Perfect for weather monitoring, automated plant watering systems, car windshield wipers, and leakage detection. Compatible with Arduino and other microcontrollers.
