I'm doing a university project using a raspberry pi 3 using , and I'm essentially making a time lapse camera. I have the camera module, and I've managed to take some pictures, but it would be good for my project if I could also get an idea of how much energy my project was using for my report. Does anyone know if the Pi has the hardware necessary to do that or a library I could reference?
When I tried to look it up myself, I saw mainly projects of using the Pi to track some other device's power usage. I could totally design a circuit that would allow me to measure voltage and current draw, but I'd rather not if the Pi is capable of doing so on its own. I know that most laptops do have a utility for it buried somewhere in the OS, and I'd rather not reinvent the wheel if I can avoid it. Thanks!
