Features:
1. The sensor uses high quality FR - 04 double material, large area of 5.5*4.0CM, nickel plating and surface treatment, has better performance in combat oxidation, electrical conductivity, and longevity.
Potentiometer sensitivity adjustment 2.With
3. Output format: digital switch output (0 and 1) and analog AO voltage output.
Fixed bolt hole, convenient installation 4. Has.
5 The comparator output provides a strong drive, clean and good waveform for more than 15 mAh capacity.
6 LM393, use a wide voltage comparisor;
5V 3.3V 7 Operating Voltage
Usage:
- Connect to the 5V power supply lamp, the induction plate has water droplets and the DO output for high level, the switch does not light up droplets of water drop, and the switch indicator will leave the water away and return to the output high level.
- AO analog output can be connected to the microcontroller AD drip of the above size rainfall
- DO TTL digital output can also connect a microcontroller to detect whether rain or not.
