Humidity Detection Sensor Module Rain Detection (Black)

Description: Connect the 5V power source, the power indicator is on, and when there is no water drop on the sensor board, the DO output is high, the switch indicator is off, and when there is a water drop, the DO output is low, and the switch indicator is on. Clean the water droplets on it, then return to the high level state of the output. The analog AO output can be connected to the AD port of a single-chip microcomputer to detect the amount of rain falling on it. The digital DO TTL output can also be connected to the microcontroller to detect whether there is rain. Features: 1. The sensor uses high-quality double-sided FR-04 material, a large area of 5.0 * 4.0cm, and the surface is treated with nickel plating, which has superior performance in terms of oxidation resistance, conductivity, and lifespan. 2. Comparator output, clean signal, good waveform, strong driving capacity, more than 15mA. 3. Adjust the sensitivity of the power distribution positioner. 4. Operating voltage 3.3V-5V. 5. Output form: digital switch output (0 and 1) and analog voltage AO output. 6. With fixing bolt holes for easy installation. 7. Small size PCB: 3.2cm x 1.4cm. 8. Uses the LM393 wide voltage comparator. Applications: Can be used in robot arrays, raindrops, and rain sensors to monitor various weather conditions and convert them into digital signals and AO outputs. Wires: 1. VCC: Connect to the positive pole of the power supply (3-5V). 2. GND: Connect to the negative pole of the power supply. 3. Is: TTL switch signal output. 4. AO: analog signal output. Package includes: 1 sensor board, 1 control panel, 2 Dupont wires of 20cm.
