Rain Drop Sensor Module
The sensor uses high quality FR-04 double-sided materials, large area of 5.0 * 4.0CM, and nickel-plated surface, with oxidation resistance, conductivity, and life expectancy superior performance.
Comparator output, the signal clean, good waveform, strong driving ability, more than 15mA
The raindrop board and the control board are separate, easy to lead the line. Brush the water droplets off and return to the high level.
TTL level output, TTL output valid signal is low. Drive capacity of about 100MA, direct drive relays, buzzers, small fans, and so on.
Adjust sensitivity by potentiometer, fixed bolt holes for easy installation. The DO TTL digital output can also be connected to a microcontroller to detect rain.
