       Product description:
The robot kit, rain, rain sensor, can be used to monitor various weather conditions and turn into several fixed output signals and AO.(MH-series Flying Fish module,Raindroops module MH-RD)

1, the sensor uses high-quality double-sided FR-04 material, the area of 5.4cm x 4.0cm, nickel-plated surface, effective oxidation, conductivity, performance and life expectancy;
2, the comparator output signal clean waveform is good, driving ability, than 15mA;
3, power level adjustment sensitivity;
4, working voltage 3.3V-5V
5, output format: digital switch output (0 and 1) and analog voltage output AO;
6, with bolt holes for easy installation
7, small board PCB size: 3.2cm x 1.4cm
8, using a wide voltage LM393 comparator

     Connect 5V power supply, power indicator light, when the sensor board does not fall, the DO output is high, the switch is off, a drop of water drops, the DO output is low, the switch indicator light is on,
The water droplets above the brush have returned to the output high state. . . .
The AO analog output can be connected to a microcontroller to detect rain drops on the AD port of the above size.
The DO TTL digital output can also be connected to the microcontroller to detect if there is rain.
