Comidox 4PCS Raindrop Detection Sensor Module Humidity Rain Weather Sensitivity Monitoring Module 3.3V-5V For Arduino

Specifications: Working voltage: 3.3V-5V Output form: digital switching output (0 and 1) and analog AO voltage output Small board PCB size: 3.2cm x 1.4cm (1cm=0.393inch) Instructions for use: Connected to the 5V power supply, the power indicator light is on, when there is no water droplet on the sensor board, the DO output is high level, the switch indicator light is off, a drop of water is dropped, the DO output is low level, the switch indicator light is on, and the water drop on the brush is removed. It returns to the output high state again. AO analog output, you can connect the AD port of the microcontroller to detect the amount of rain on the drop. The DO TTL digital output can also be connected to a microcontroller to detect rain. Wiring: VCC: Connect the positive pole of the power supply (3-5V) GND: Connect the negative pole of the power supply DO: TTL switch signal output AO: analog signal output Note: The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully! Manual measurement, with small error. Please check size in detail before purchase. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.
