ADEEPT Ultimate Sensor Kit for Raspberry Pi - Lesson 30 Water Level Detection; Experimental Procedures

Lesson 30 Water Level Detection
Introduction
The module is a simple water level sensor. It measures the water volume by the printed
wires exposed to the air on the module. The more water on the surface, more wires
connected. Thus, the area of electrified wires gets larger, so the output voltage will
increase. The surface of the sensor is gilded to prolong its life.
