I will define each and every step of code and circuit thoroughly and deeply with logic. In this tutorial i will define the best method and precise formula generation for measuring dc current with acs712 current sensor. So i decided to write a tutorial on acs712 current sensor and put forward a practical example with circuit and code. I found that all of them are measuring current with formulas(derived for acs712 current sensor) which are not precise. I have gone through various blogs on internet about interfacing acs712 current sensor with arduino and other microcontrollers. Acs712 can measure current precisely and accurately if properly managed. In this tutorial, I am going to measure DC current using Acs712 Hall Effect-Based Linear Current Sensor and arduino uno.
