Rain Sensor Water Raindrops Detection Module for arduino DIY KIT

Description

The sensor USES the high quality FR – 04 double material, large area of 5.5 * 4.0CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance
With potentiometer sensitivity adjustment
The output format: digital switch output (0 and 1) and analog AO voltage output
Has a fixed bolt hole, convenient installation
The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA
The LM393, use of wide voltage comparator
The working voltage of 3.3 V to 5 V
Size: Like the picture show

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.
