Description
Product Usage:
The
robot kit, raindrops, and rain sensors can be used to monitor various
weather conditions and convert them into digital signals and AO outputs.
product description:
2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA;
3. Adjusting the 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. Equipped with fixing bolt holes for easy installation
7. Small board PCB size: 3.2cm x 1.4cm
8. Use a wide voltage LM393 comparator
Features:
Connect
the 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, the DO output is low
level, and the switch indicator light is on.
Brush off the water droplets on it, and then return to the output high-level state. . . .
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:
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
