Arduino Raindrop Sensor Module YL83

Rain Sensor can read an analogue value on the sensor output pin as a result of the contact of conductive lines drawn in parallel with each other with water. It can be used with other development boards and microcontrollers other than Arduino. The module provides both digital and analogue output. According to the needs of your project, you can measure the rain intensity or whether it is raining with analogue signals from pin A0 or digital signals from pin D0.

Features:

1.The sensor USES the high quality FR - 04 double material, large area of 5.0 * 3.8CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance;
2.With potentiometer sensitivity adjustment;
3.The output format: digital switch output (0 and 1) and analog AO voltage output;
4.Has a fixed bolt hole, convenient installation;
5.The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA;
6.The LM393, use of wide voltage comparator;
7.The working voltage of 3.3 V to 5 V;
8.Sensor Area: 50x38x10mm

Usage:

- Connected to 5 v power supply power lights, no water droplets on induction plate, the DO output for the high level, switch lights out, a drop of water drops, the DO output for the low level, switch indicator, brush away the water droplets, return to again, the output high level state.
- AO analog output, can be connected to the microcontroller AD mouth drops of rainfall in the above size.
- DO TTL digital output can also be connected microcontroller detecting whether it will rain.
