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.
