Raindrops Detection sensor

Item Description:
3.3-5V Rain Raindrop Detection Sensor Module

Features:

• The sensor USES the high quality FR - 04 double material, large area of 5.5 * 4.0CM, treatment of nickel plating and surface give it low oxidation, electrical conductivity, and longer life with superior performance;
• 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;
• Uses a LM393 for a wide voltage range comparator;
• Working voltage of 3.3 V to 5 V
  
   

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.
