Description:
100% brand new and high quality
Product Usage:
Arduino robot kit, raindrops, rain sensors, can be used for monitoring a variety of weather conditions, and turn into a fixed number of signals and AO output.
product description:
1, the sensor uses high-quality FR-04 double-sided materials, large area 5.0 * 4.0CM, and nickel-plated surface, with oxidation resistance, conductivity, and life expectancy superior performance;
2, the comparator output, the signal clean, good waveform, strong driving ability, more than 15mA;
3, with the potentiometer to adjust the sensitivity;
4, working voltage 3.3V-5V
5, the output form: digital switch output (0 and 1) and analog AO voltage output;
6, with a fixed bolt hole for easy installation
7, small board PCB size: 3.2cm x 1.4cm
8, using a wide voltage LM393 comparator
Features:
Connected to the 5V power supply, the power indicator light, no water droplets on the sensor board, DO output is high, the switch indicator off, a drop of water, DO output is low, the switch indicator light,
Brush off the water droplets above, and returned to the high output state. . . .
AO analog output, you can connect the microcontrollers AD port drops in the above rainfall.
DO TTL digital output can also be connected to the microcontroller to detect whether there is rain.

Wiring:
1, VCC: Positive power supply (3-5V)
2, GND: connect the negative power supply
3, DO: TTL switch signal output
4, AO: analog signal output
Color: Random delivery, so we do not offer color choice.
Package include:
1x rain sensor board
1x control panel
