Weather Raindrop Rain module Rain sensor Leaf sensor module Highly sensitive

Product Usage: Raindrops, rain sensors, can be used to monitor various weather conditions and convert to digital signals and AO outputs.
product description:
1. The sensor adopts high-quality FR-04 double-sided material, with a large area of?? 5.0 * 4.0CM, and is treated with nickel-plated surface, which has superior performance against oxidation, electrical conductivity and life; 2, the comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA; 3, with potentiometer adjustment sensitivity; 4, working voltage 3.3V -5V
5.
Output form: digital switch output (0 and 1) and analog AO voltage output; 6, with fixed bolt holes for easy installation 7, small board
PCB size: 3.2 cm x 1.4 cm 8, using a wide voltage LM393 comparator
Features: Connected to the 5V power supply, the power indicator light is on, when there is no water droplet on the sensor board, the DO output is high level, the switch indicator light is off, a drop of water is dropped, the DO output is low level, and the switch indicator light is on. Brush the water droplets above and return to the high level state.... AO analog output, you can connect the AD port of the microcontroller to detect the amount of rain on the drop. The DO TTL digital output can also be connected to a microcontroller to detect rain.
Wiring: 1.
VCC: Connect the positive pole of the power supply (3-5V) 2, GND: connected to the negative power supply 3, DO: TTL switch signal output 4, AO: analog signal output
