Hello, I am working on a system with many sensors, also with data storage and transmission. For its operation I must guarantee an autonomy of 5 days, therefore to estimate the battery bank I need to know the energy consumption. Do you know the way to record energy consumption over time?
It’s expensive, but the most accurate power measurement would be with the Otii Arc (Otii Arc)
Please note that when powering the device via USB you won’t see the same current measurements as indicated in the datasheet. Those reference Li+ as the power source. When using VIN/USB power the PMIC never fully turns “off” if the device is sleeping.
