3.3-5V Rain Raindrops Detection Sensor Weather Humidity Module For Arduino
- 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;
– 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.
