ABOUT THIS PROJECT

This project aimed to meet the requirements of the

science fair that happened in my city Our

electroconductivity sensor was designed as a simple

way to measure the amounts of dissolved substances

in different water samples. It can also be used as a

(short-term) soil moisture sensor!

This sensor is made of two wires separated by an air

gap. The air gap allows us to test how well a material

or substance conducts electricity.
