Liquid Sensor
Product Details
Arduino robot kit, raindrops, rain sensor can be used to monitor a variety of weather conditions, and converted into the number of the reference signal and the output AO.
Product description:
1, sensor uses high-quality double-sided FR-04 material, the large area of 5.0 * 4.0CM, with nickel plated surface, electrical conductivity, and superior lifetime performance;
2, the comparator output signals clean, good waveform, driving ability, more than 15mA;
3, sensitivity adjustment;
4, working voltage of 3.3V-5V
5, output form: digital switching output (0 and 1) and analog AO voltage output;
6, a fixed bolt hole for easy installation
7, small PCB board size: 3.2cm x 1.4cm
8, using a wide voltage comparator LM393
Features:
When connected to the 5V power supply, power indicator light, dry sensing plate, DO output is high, switch lights off, dripping a drop of water, DO output is low, switch indicator light on,
dry off water droplets, it will return to output high state. . . .
AO analog output can be connected to the microcontroller AD port to detect drops in the above rainfall size.
DO TTL digital outputs can also be connected to the microcontroller to detect whether there is is rain.
Wiring:
1, VCC: positive power supply (3-5V)
2, GND: negative one
3, DO: TTL switching signal output
4, AO: analog output
