XLX 5 Sets Rain Drops Sensor Module Weather Detection MonitorLarge Area Raindrop Module Highly Sensitive HumidityHigh Efficient 3.3~5V for Arduino Weather

Sensor performance and features: -The sensor adopts high-quality FR-04 double-sided material, with a large area raindrop testof 5.4*4.0CM, more conducive to the detection of rain. and is treated with nickel-plated surface, which has superior performance against oxidation, electrical conductivity and life - The comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA - Adjust sensitivity with potentiometer - Voltage: 5V -Output form: digital switch output (0 and 1) and analog AO voltage output; -with fixed bolt holes for easy installation -PCB size: 5.5cm x 4cm -Function: Use wide voltage LM393 comparator function introduction: Connect 5V power supply, power indicator light is on, there is no water drop on sensor board, DO output is high level, switch indicator is off, drop a drop of water, DO output is low level The switch indicator light is on, brush the water drop above, and 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 rainfall dripping on it. The DO TTL digital output can also be connected to a microcontroller to detect rain. -Power indicator, output signal LED indicator -No rain when the LED light output is high, the raindrop up, the output level, LED light -Board with positioning holes for everyone to install Wiring: 1. VCC: positive power supply (3-5V) 2. GND: power supply is negative 3. DO: TTL switching signal output 4. AO: analog signal output Package Included: 5* Rain Drops Sensor board 5 * Control board 10 * 20cm Cable wires
