|Features||Arduino rain sensor module|
|Specification||Working voltage: 3.3V~5V; Wiring: 1. VCC: connect to positive power supply (3~5V); 2. GND: connect to negative power supply; 3. DO: TTL switching signal output; 4. AO: analog output|
|Application||Arduino robot kits, rain, rain sensor, can be used to monitor a variety of weather conditions, and turned into several fixed output signal and AO|
|Other||A product for Arduino that works with official Arduino boards. The sensor uses a high-quality double-sided FR-04 materials, the large area of 5.0 x 4.0cm, and nickel-plated surface, effective against oxidation, conductivity, superior performance and lifetime areas; The comparator output signal clean waveform is good, driving ability, than 15mA; Power bits adjust the sensitivity; Working voltage: 3.3~5V; The output format: Digital switching output (0 and 1) and analog voltage output AO; With bolt holes for easy installation; A small board PCB size: 3.2cm x 1.4cm; Using a wide voltage LM393 comparator; Connect the 5V power supply, power indicator light, sensor board does not drop, DO output is high; The switch lights off, dripping a drop of water, DO output is low, the switch indicator light; Brush above water droplets, has returned to the output high state; AO analog output can be connected to the microcontroller detects AD mouth drops of rain in the above size; DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain|
