- Arduino robot kits, raindrops, rain sensor can be used to monitor a variety of weather conditions,
- and turn into a number of the reference signal and the output AO.
product description:1, sensor FR-04 double-sided high-quality materials, large area of ??5.0 * 4.0CM, and nickel-plated surface, with antioxidant, electrical conductivity, and superior lifetime performance;2, the comparator output signal clean, good waveform, driving ability, than 15mA;3, distribution positioner sensitivity adjustment;4, the working voltage of 3.3V-5V5, the output format: Digital switching output (0 and 1) and analog voltage output AO;6, a fixed bolt hole for easy installation7, small plates PCB size: 3.2cm x 1.4cm8, using a wide voltage comparator LM393Features:When connected to 5V power supply, power indicator light, no water induction plate, DO output is high, switch lights off, dripping a drop of water, DO output is low, the switch indicator light,Brush the top of the drop, and return to the output high state. . . .AO analog output can be connected to the microcontroller AD port to detect drops in rainfall above size.DO TTL digital outputs can also be connected to the microcontroller to detect whether there is rain.Wiring:1, VCC: positive power supply (3-5V)2, GND: power supply is negative3, DO: TTL switching signal output4, AO: Analog outputmodule * 1
