โมดูลเซนเซอร์ตรวจสอบน้ำฝน Rain sensor module

Product Usage:Arduino

Rain sensor can be used to monitor a variety of weather conditions, and converted into the number of the reference signal and the output AO. for  Arduino robot kit, raindrops

product description:

1.sensor uses high-quality double-sided FR-04 material, the large area of 5.0 * 4.0CM, with nickel plated surface, with antioxidant, electrical conductivity, and superior lifetime performance;

2.the comparator output signals clean, good waveform, driving ability, than 15mA;

3. distribution position sensitivity adjustment;

4. the working voltage of 3.3V-5V

5.the output form: digital switching output (0 and 1) and analog AO voltage output;

6.a fixed bolt hole for easy installation

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

8. using a wide voltage comparator LM393

Features:

When connected to the 5V power supply, power indicator light, no water induction plate, DO output is high, switch lights off, dripping a drop of water, DO output is low, the switch indicator light,

Brush the top of the water droplets, it has returned to output high state. . . .

AO analog output can be connected to the microcontroller AD port to detect drops in the above rainfall size.

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

Wiring:

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

2, GND: negative one

3, DO: TTL switching signal output

4, AO: analog output
