Giới thiệu Mô-đun cảm biến mưa DC 3.3V-5V 3.3-5V tại Lotte Market

Product Usage:
Arduino robot kit, raindrops, rain sensor, can be used to monitor various weather conditions, and converted into digital signal and AO output.

product description:
1. The sensor adopts high-quality FR-04 double-sided material, a large area of ​​5.0*4.0CM, and the surface is treated with nickel plating, which has better performance in terms of oxidation resistance, conductivity, and life;
2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA;
3. Adjust sensitivity of power distribution positioner;
4. Working voltage 3.3V-5V
5. Output form: digital switch output (0 and 1) and analog AO voltage output;
6. With fixing bolt holes for easy installation
7. Small board PCB size: 3.2cm x 1.4cm
8. Use wide-voltage LM393 comparator function introduction: connect 5V power supply, the power indicator light is on, when there is no water drop on the sensor board, the DO output is high level, the switch indicator light is off, a drop of water is dripped, and the DO output is low level , The switch indicator light is on, the water droplets on it are brushed off, and the output is high again. . . . The AO analog output can be connected to the AD port of the microcontroller to detect the amount of rain falling on it. The DO TTL digital output can also be connected to the microcontroller to detect whether there is rain.

Wiring mode: 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. DO: TTL switch signal output 4. AO: analog signal output
