The rain sensor module is an easy tool for rain detection. The module features, a rain board and the control board that is separate for more convenience, power indicator LED and an adjustable sensitivity though a potentiometer.
Specifications:
- Area: 5cm x 4cm nickel plate on side,
- Anti-oxidation, anti-conductivity, with long use time;
- Comparator output signal clean waveform is good, driving ability, over 15mA;
- Potentiometer adjust the sensitivity;
- Working voltage 5V;
- Output format: Digital switching output (0 and 1) and analog voltage output AO;
- With bolt holes for easy installation;
- PCB size: 3.2cm x 1.4cm;
- Uses a wide voltage LM393 comparator.
Features:
- DO output is high, the switch indicator is off, a drop of water drops, DO output is low, the switch indicator light, the output indicator light is on,
Brush the water droplets above, and back to the output high state. . . .
- AO analog output, you can connect the microcontroller's AD mouth to detect drops in the above rainfall.
- DO TTL digital output can also be connected to the microcontroller to detect whether there is rain.
Wiring:
- VCC: Connect the positive pole of the power (3-5V)
- GND: Connect the negative pole of the power supply
- DO: TTL switch signal output
- AO: analog signal output
