Product Usage:

Arduino robotic kits, raindrops, rain sensors, can be used for monitoring of various weather conditions and turn into numbered signals and AO outputs.

product description:

1, the sensor uses high-quality FR-04 double-sided material, large area of ​​5.0 * 4.0CM, and nickel-plated surface, with anti-oxidation, conductivity, and life more superior performance;

2, the comparator output, the signal clean, good waveform, drive ability, more than 15mA;

3, with the potentiometer to adjust the sensitivity;

4, the working voltage of 3.3V-5V

5, the output form: digital switch output (0 and 1) and analog AO voltage output;

6, with a fixed bolt hole, easy to install

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

8, using a wide voltage LM393 comparator

Features:

Connected to the 5V power supply, power indicator light, no water droplets on the sensor board, DO output is high, the switch indicator light off, drop a drop of water, DO output is low, the switch indicator light,

Brush the water droplets above, and return to the output high state. The The The

AO analog output, you can connect the microcontroller's AD port to detect the amount of rainfall in the above.

DO TTL digital output can also be connected to the microcontroller to detect whether there is rain.

Wiring:

1, VCC: then the power supply positive (3-5V)

2, GND: Connect the power supply negative

3, DO: TTL switch signal output

4, AO: analog signal output
