Rain and snow detector module for Arduino

Robot kits, rain, rain sensor, can be used to monitor a variety of weather conditions, and turned into several fixed output signals and an AO.

1, the sensor uses a high-quality double-sided FR-04 material, a large area of 5.0'' x 4.0 cm, and a nickel-plated surface, effective against oxidation, with superior conductivity, performance, and lifespan;

2, the comparator output signal has a clean, good waveform and driving ability of more than 15 mA;

3, power bits adjust the sensitivity;

4, Working voltage 3.3V-5V

5, the output format: digital switching output (0 and 1) and analog voltage output AO;

6, with bolt holes for easy installation

7, a small board; PCB size: 3.2 cm x 1.4 cm

8, using a wide voltage LM393 comparator

Connect the 5V power supply; the power indicator light is on when the sensor board is not wet. The DO output is high, and the switch light is off. When a drop of water is dripping, the DO output is low, and the switch indicator light is on.

After the water droplets are brushed away, the output returns to a high state.

The AO analog output can be connected to a microcontroller's AD input to detect the amount of rainfall.

The DO TTL digital output can also be connected to a microcontroller to detect whether it is raining.
