Foliar rain sensor module sensitive sensor module


Product Use:

Robot kits , rain , rain sensor , can be used to monitor a variety of weather conditions , and turned into several fixed output signal and AO .

Product description:

1.  The sensor uses a high-quality double-sided FR-04 materials, the large area of 5.0\'\' 4.0CM, and nickel-plated surface, effective against oxidation, good conductivity, superior performance and lifetime areas ; 

2.  The comparator output signal clean waveform is good, driving ability, than 15mA;

3.  Power bits adjust the sensitivity;

4.  Working voltage 3.3V-5V

5.  The output format : Digital switching 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


AO analog output can be connected to the microcontroller detects AD mouth drops of rain in the above size.

DO TTL digital outputs can also be connected to the microcontroller to detects whether there is rain . 


1, VCC: positive power supply (3-5V)

2, GND: tied to power supply

3, DO: TTL switching signal output

4, AO: analog output
