Water Lever Detection Sensor Module 1
Component Introduction
The water sensor water level module can perceive water by
measuring the volume of droplets water through a series of
parallel lines exposed traces in order to determine the water
level.
W hen insert it into the water, those parallel lines will generate a resistor that can change along
with the depth of water. Then, the signal of water's depth is converted into the electrical signal,
and we can get the changes through the ADC function from UNO R3 or MEGA 2560.
