Product use:

Arduino robot kit, rain drops, rain sensors, can be used for monitoring of various weather conditions, and converted into a number signal and AO output.

Product introduction:

1. The sensor uses high-quality FR-04 double-sided material, with a large area of ​​5.0*4.0cm, and is treated with nickel-plated surface. It has a better performance in combat oxidation, conductivity, and life span;
2. The output of the comparator, the signal is clean, the waveform is good, and the driver capacity is strong, exceeding 15mA;
3. Adjust the sensitivity of the power distribution position;
4. Work voltage 3.3V-5V
5. Output form: Digital switching output (0 and 1) and analog AO voltage output;
6. There are fixed bolt holes for easy installation
7. Small board PCB size: 3.2cm x 1.4cm
8. Use width voltage LM393 comparator

Function introduction:

Connect the 5V power supply, the power indicator light is bright, 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,
Brush off the water droplets above and return to the high level of output.EssenceEssenceEssence
AO 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 method:

1. VCC: Positive power supply positive (3-5V)
2. GND: connected to the negative power supply
3. Do: TTL switch signal output
4, AO: analog signal output
