    DC Energy Measurement Using INA226

    In an earlier post I wrote about measuring DC energy using PZEM 017. If you recall, I ended the article with a couple of remarks. One was that the device was unable to measure current below 0.02 A. But the bigger problem was that the device could only measure current in one direction. It is uni-directional current sensor. I cannot use this device with my UPS to measure charging and discharging current since I need a bidirectional current sensor in that case. After some searching around I found a few options and one good sensor which is the INA226. So here is a write up of my experience with it. This can get a bit technical, so if you are not into electronics, give this a skip.
