Raindrop Sensor Module

Features
1. A raindrop sensor to detect whether it is raining and also the rainfall. The raindrop sensor module and the analyser are made separately for convenient wire leading.
2. Use a comparator chip which gives outputs a clean and stable digital signal and features a driving ability of 15 mA.
3. Adopt a comparator LM393 to output both digital and analog signals at the same time.
4. With power light and signal output indicator; adjustable sensitivity by a potentiometer.
5. Working voltage: 3.3-5V DC; PCB size: 3.3 x 4.6 cm.

Product Description

Details

Introduction
When wired with a 5v supply, the power light will be on. When the sensor detects no raindrop, D0 is high and the indicator keeps out. Drop some water onto the sensor. The more drops, the lower value at A0. When the value of A0 is smaller than the value set, D0 will change from high to low and the indicator will light up.

Application
It is widely used in the automatic wiper system, smart lighting system and sunroof system of automobiles.

I powered it from 3.3V and it triggers a GPIO pin change when it reads water. It does not send 3.3V back but my Python code did detect the edge change. By Rhoda Baade 2016-05-19 05:58:52

Bought this as a sensor to use from my Raspberry PI to monitor my sump
pit. It works great with the PI for detecting the presence of water or
not. The water has to take up an entire row and not just a splash on
the sensor. The PI cannot read voltage changes but I hooked it up to
my multimeter and you can see the voltage change as the depth changes
so any device that can read that could get extra information from this
sensor.
