Snow Raindrops Humidity Rain Weather Detect Sensor Module For Arduino


  • INR: ₹ 250.00

The item is for Arduino robot kit, raindrops& rain sensor. Monitoring can be used for a variety of weather conditions and it converted  the number of the reference signal and the AO output.
The sensor uses the FR-04 high-quality double-sided materials, King Size 5.0 * 4.0CM, and with the surface of the nickel plating treatment against oxidation, conductivity, superior performance and longevity;
The output is in the form of  : digital switching outputs (0 and 1) and analog AO voltage output;
TTL-level output, TTL output valid signal is low. Driving capability 100MA, so it can directly drive relays, buzzer, a small fan, and so on.
Sensitivity can be adjusted via potentiometer
LED glows when there is no rain drops and the output is high,as the raindrops falls  the output reaches to ground level.



Small board PCB size: 3.2cm x 1.4cm
Operating voltage: 3.3V-5V
Voltage: 5V

Distribution bit to adjust sensitivity
A fixed bolt hole for easy installation
Power indicator, the output signal LED indicator
The comparator output, the signal is clean, waveform, driving ability over 15mA
Wide voltage LM393 comparator
A large area of ​​rain board, more appropriate to detect rain
Board with positioning holes to facilitate installation
Raindrops and control panels are separate

How to use:

Connect to a 5V power supply, when there is no water droplets on  the sensor board it shows light and the output is high as soon as the water droplets starts dropping on the sensor board the lights automatically switched off and the DO output start decreasing. As soon as u brush off the water droplets the light starts glowing and the DO output is increased as before.
AO analog output can be connected to the microcontroller AD port to detect the size of the drops in the above rainfall.
DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain or not.
