Description:

• 100% brand new and high quality
• Material: Electronic component
• Color: See pictures
• Arduino Robot Kit, Raindrops, Rain Sensor, can be used for various weather conditions monitoring, and converted into a fixed signal and AO output.
• Product Description:
• 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;
• The comparator output, the signal clean, good waveform, driving ability, more than 15mA;
• With the potentiometer adjustment sensitivity;
• The working voltage of 3.3V-5V
• The output form: digital switch output (0 and 1) and analog AO voltage output;
• With a fixed bolt hole, easy to install
• Small board PCB size: 3.2cm x 1.4cm
• 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:
• VCC: Connect the positive pole of the power (3-5V)
• GND: Connect the negative pole of the power supply
• DO: TTL switch signal output
• AO: analog signal output
