Product introduction

This analog conductivity meter has the characteristics of simple connection, convenient and practical.After connecting according to the schematic diagram, and then through program control, it is very convenient to measure the conductivity of the solution.

The most important thing is that we open source all the design and code. Users can easily collect conductivity data through Arduino for further control and research. Fans are welcome to research and share and provide valuable feedback.

Conductivity is the ability of a substance to carry a current and is the reciprocal of resistivity. In the liquid, the electrical resistance of the electrical resistance is often measured by the reciprocal of the electrical resistance. The conductance of water is a very important indicator of water quality, and it reflects the extent of electrolytes present in the water. The degree of conductivity of the solution varies depending on the concentration of the electrolyte in the aqueous solution. In the International System of Units, the unit of conductivity is called Siemens/meter (S/m), and other units are: S/m, mS/cm, μS/cm.
