Description
Rain Drops Detection Sensor can be used for all kinds of weather monitoring, and translated into output signals and AO.
- The sensor uses the high quality FR – 04 double material, large area of 5.5 * 4.0 CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance;
- The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA;
- With potentiometer sensitivity adjustment
- The working voltage of 3.3 V to 5 V
- The output format: digital switch output (0 and 1) and analog AO voltage output;
- Has a fixed bolt hole, convenient installation
- Small board PCB size: Approx. 3.2 cm x 1.5 cm
- The LM393, use of wide voltage comparator
Terminals:
- VCC: positive (3-5 v)
- GND: connect power anode
- DO: TTL switch signal output
- AO: analog signal output
