Water Level Indicator Circuit Using Bipolar Junction Transistor

by Manikandan KJ

Overview

Many circuits related to water level sensing/control are easily available on the internet, but the major drawback of all circuits which uses a metal probe as sensors is electrolysis. Electrolysis does not take place in circuits which uses a float switch or other sensors, but they are costly compared to circuits which use metal probes. Pure waters are bad conductors of electricity but unfortunately not all water we use are 100% pure. Moreover, in 100% pure water, water level sensing (which uses metal probes) does not work too!
Here is a simple water level indicator circuit with minimized electrolysis.

About the Author

I am quite interested in electronics, as well as computers and Ayurveda. I like acquiring new knowledge, expanding my knowledge base, learning new skills, and then applying those skills to something else. Since 2010, I have been involved in both buying and selling online. I sell simple electronic circuit boards that I develop and build. A variety of electronic circuit boards may be purchased from my online store in India, which can be found at kjmindia(dot)in. I want to gain information from the experiences that other people have shared with me, and in exchange, I want to impart that knowledge and experience to the rest of the world.
