เซนเซอร์น้ำฝน ความชื้น Raindrops Detection Sensor Module Rain Weather Module Humidity

3.3-5V Rain Raindrops Detection Sensor Humidity Module For Arduino

attribute:

1. The sensor uses high-quality FR - 04 double material, a large area of 5.5 * 4.0cm, nickel-plated treatment, and the surface has anti-oxidation, conductivity, and better life performance.
2.Potentiometer sensitivity adjustment;
3. Output form: digital switch outputs (0 and 1) and analog voltage AO outputs;
4. There is a fixed bolt hole, convenient installation;

5. Comparator output, clean signal, good waveform, strong driving ability for more than 15 mA;
6.LM393 uses a wide voltage comparator;
7. Supply voltage 3.3 V to 5 V;
Size: like the picture show

Usage:

-Connect 5V power, no water droplets induction plate, DO output high level, light switch OUT, water drop drops DO for low level, switch on, brush away the water droplets, return to again, drop out. High level output state.
-AO ANALOG OUTPUT, can connect the microcontroller AD mouth dripping rain in size.
-DO TTL digital output can be connected to the microcontroller to detect whether it will rain.
