Rain Sensor Module

Rain Sensor Module

Feature:

• Working Voltage: 3.3 V- 5V
• The sensor USES the high quality FR - 04 double material, large area of 5.5 x 4.0 CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance
• The LM393, use of wide voltage comparator
• The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA.
• With potentiometer sensitivity adjustment
• Has a fixed bolt hole, convenient installation
• Weight: 30 gr

Function:

•  Connected to 5 v power supply, power indicator, no water droplets on induction plate, the DO output high level, switch indicator light out, drop a drop of water on, the DO output for the low level, the switch light is lit,Brush away the water droplets, again to return to, the output high level
•  AO analog output, which can be connected to the microcontroller AD mouth detection drops of rainfall in the above size
•  DO TTL digital output also can connect to the single chip microcomputer detect whether there is rain

 
Connection mode

• VCC: Positive (3-5 v)
• GND: Connect power anode
• DO: TTL switch signal output
• AO: Analog signal output
