Description:

Brand new Water Level Alarm Sensor Module Liquid Level Sensor Circuit Board

This sensor module can estimate the water level through a series of exposed parallel conductor line marks measuring the water droplets and capacity

Easily convert water to analog signal, the output analog signal can be read directly on the arduino board to achieve the effect of water level alarm

The surface have gone through plating processing to enhance the electrical conductivity and corrosion resistance

Simple circuit and easy to use and high cost performance
