Rainwater Sensor

Description

Product Usage: Arduino robot kit, raindrops, and rain sensors can be used for monitoring various weather conditions and converted into a number signal and AO output.

product description. The sensor uses FR-04 double-sided material, with an area of 5.0*4.0cm, and is treated with a nickel plating surface, which has more performance in combat oxidation, conductivity, and life. Strong ability, exceeding 15mA; 3. The power distribution position regulating sensitivity; 4. Work voltage 3.3V-5V 5. Output form: Digital switch output (0 and 1) and analog AO voltage output; 6. There are fixed bolts with fixed boltsPole, convenient installation 7, small board PCB size: 3.2cm x 1.4cm 8. Use wide voltage LM393 comparator features: Connect the 5V power supply, the power indicator light is on, and when there is no water droplet on the inductive board, the DO output is high level, the switch indicator light is extinguished, a drop of water, the DO output is low level, the switch indicator light is on, and the water droplets on it are brushed off. It is restored to the output high-level state.EssenceEssenceEssenceAO simulation output can connect the amount of rain on top of the AD port of the single-chip microcomputer. Do TTL digital output can also connect the single-chip microcomputer to detect whether there is rain.

Wiring:1. VCC: Positive power supply (3-5V) 2. GND: Connect the power supply. Do: TTL switch signal output4, AO: analog signal output

Shipping list: 1. As shown in Figure, 2, 20cm DuPont lines on each of the raindrop sensing board and the control board are convenient for wiring
