Rain Water Sensor Module Rain Weather Module

Product Usage: Robot kit, raindrops, rain sensors, can be used for a variety of weather conditions monitoring, and turned into a fixed number of signals and AO output. product description: 1, the sensor uses high-quality FR-04 double-sided material, large area 5.0 * 4.0CM, and nickel-plated surface treatment, with anti-oxidation, electrical conductivity, and life better performance; 2, the comparator output, the signal clean, good waveform, driving ability, more than 15mA; 3, with the potentiometer adjustment sensitivity; 4, the working voltage of 3.3V-5V 5, the output form: digital switch output (0 and 1) and analog AO voltage output; 6, with a fixed bolt hole, easy to install 7, small board PCB size: 3.2cm x 1.4cm 8, the use of wide voltage LM393 comparator Features: DO output is high, the switch indicator is off, a drop of water drops, DO output is low, the switch indicator light, the output indicator light is on, Brush the water droplets above, and back to the output high state. . . . AO analog output, you can connect the microcontroller's AD mouth to detect drops in the above rainfall. DO TTL digital output can also be connected to the microcontroller to detect whether there is rain. Wiring: 1, VCC: Connect the positive pole of the power (3-5V) 2, GND:Connect the negative power supply 3, DO: TTL switch signal output 4, AO: analog signal output
