Hey #electronics folks! <3 I want to build a CO2 sensor with a battery life of several months. First using prototyping boards, then maybe as a custom PCB.

Some questions:

1. What kind of approach/device would you suggest to measure the power consumption of such a device? I hope to end up in the single-digit mW range.

2. What would be the lowest-power components required to drive a small e-ink screen?

3. Does the 328P seem like a suitable controller, if I don't need any connectivity?
