Product Introduction
Connect a 5V power supply, the power indicator light is on, and when there are no water droplets on the induction board, the DO output is at a high level, and the switch indicator light is off. Drip a drop of water, the DO output is at a low level, the switch indicator light is on, brush off the water droplets on top, and return to the output high level state. AO analog output can be connected to the AD port of the microcontroller to detect the amount of rainfall falling on it. DOTTL digital output can also be connected to a microcontroller to detect rain.

Product Features

2. Comparator output, clean signal, good waveform, strong driving ability, over 15mA
3. Equipped with potentiometer to adjust sensitivity
4. Working voltage 3.3V-5V
5. Output format: Digital switch output (0-1) and analog AO voltage output
6. Equipped with fixed bolt holes for easy installation
7. Module size: 3.2 * 1.4CM
8. Using a wide voltage LM393 comparator

Product Application
Arduino robot kit, raindrops, rain sensors, can be used for monitoring various weather conditions, and converted into digital signals and AO outputs
