Description
One rain drops sensor set. The raindrop board and the control board are separate, so the sensing plate can sit outside while the control board stays dry. The nickel-plated sensing area resists oxidation, and the LM393 comparator gives a clean output with sensitivity set by a potentiometer.
This listing is for one single set: one raindrop board and one control board. Quantity 1.
- Sensing plate: 5.0 by 4.0cm, nickel-plated, double-sided FR-04 material
- Control board: LM393 comparator, separate from the sensing plate
- Operating voltage: 3.3 to 5V
- Outputs: digital DO and analog AO
- Comparator output, clean signal, strong driving ability, more than 15mA
- TTL level output, valid signal is low, drive capacity about 100mA, can directly drive relays, buzzers, and small fans
- Sensitivity adjustable with the potentiometer
In the box: 1 raindrop sensing board, 1 LM393 control board, 1 connecting cable.
