Description
Connect the 5V power supply, the power indicator is on, and when there is no water drop on the sensor board, the DO output is high, the switch indicator is off, a drop of water is dropped, the DO output is low, and the switch indicator is on.
Brush off the water droplets on it, and then return to the output high level state. . . .
AO analog output can be connected to the AD port of the single-chip microcomputer 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.
Features
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 superior 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
Applications
The robot kit, raindrops, and rain sensors can be used to monitor various weather conditions and convert them into digital signals and AO outputs.
Wiring
1. VCC:Connect 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
