![]() ![]() But I will use one IC to display 4 levels,Īs I said earlier this tutorial mainly focuses on the designing steps, so before I explain the complete circuit diagram first I would like to explain the LM339 voltage comparator IC. If you want to display all the 11 levels then you will have to use three lm339 comparator ic’s. ![]() As we will be using lm339 voltage comparator which has 4 outputs, it means we can connect 4 led’s or relays. As you can see in the table, at different voltages we have different charge percentage. I searched for a random battery and downloaded its charge Vs Voltage table. I would appreciate your support in this way! I may make a commission if you buy the components through these links. The same circuit will also be used in making a stabilizer which I will show you in upcoming tutorials.įor advanced level battery voltage monitoring systems check the related projects section given at the end of this article. In this tutorial, you will also learn how to use a voltage comparator LM339, its basic working principle, How to set the trigger voltages to show the exact charge percentage, and then how to make a final circuit. This tutorial explains the complete designing steps. This battery voltage monitor is entirely based on the LM339 voltage comparator IC. In this tutorial, we not going to use any Microcontroller. ![]()
