Introduction

Raindrop sensor module is can detect the water drop, there’s a wild sensor ins size of 5*4 cm for the ease of detecting the water drop. For the LM393, Rain drop sensor module has two types of output: analog output and digital output, when detect the rain drop, it output low level, and the indicated LED for sensor will disgusting, when there’s no water drop on the sensor, the module will output high level and light the LED.
