10pcs/lot Raindrop module Raindrop Humidity Test Sensor Module for Arduino development board FZ0806X10
Power indicator and output signal LED indicator
TTL level output, TTL output effective signal is low level. Drive force is about 100 ma, can direct drive relay, buzzer, small fan, and so on.
Sensitivity can be adjusted through the potentiometer
When no rain, LED illumination output is high level, when touched with raindrop, output low level and the LED is light up.
Raindrops board and control board are separated, convenient to lead our wires.
Carries mounting bores for easy installation
Controller board size:3*16mm
Connect it with 5V power supply and the LED indicator is on. When there is no raindrop on the sensor pad, DO output is high level, LED indicator is off.
With raindrop falled onto the sensor board, DO output is low level, and LED indicator is on.
Brush off the raindrop, it turned to high level status.
AO analog output can connect the AD interface of SCM to check the size of raindrop.
DO TTL digital output can also connect with SCM to test if there is raindrop or not.
