ATK-Raindrop Sensor Raindrop Sensor
Overview
Raindrop sensor is for the rain quantity as well as presences senor. From analog
output you can check the amount of rainfall. And from digital output you can
recognize the presence of rain water. Adjust the digital output by simply varying the
on board potentiometer.
Features
Operating voltage: 5V Provide both digital and analog output Adjustable sensitivity Output LED indicator Compatible with Arduino and Microcontroller TTL Compatible Onboard holes for easy installation

Pin Pin Name
Pin Name
+5V I/P Regulated 5V supply input
GND GND Ground level of power supply
DO O/P Digital Output to external devices
AO O/P Analog Output to ADC
Connected to 5V power supply power lights, induction board no water droplets DO output is low, the switch indicator lights off, dropping on a drop of water, DO output is high, the switch indicator lights on,
Brush off the the above water droplets, has returned to output to low state. . . . AO analog output can be connected to the MCU ADC port to detect the size of the drops in the
above rainfall. DO TTL digital outputs can also be connected to the MCU detects whether there is rain.
