Currently, this Nodemcu is used to measure the capacity from recycled 18650 notebook batteries. Values maybe empty before new battery start.

Pure Imagination is a working prototype of a future wherein plant fed microbial fuel cells cleanly generate a substantive amount of people’s daily electricity usage. This channel is regularly fed performance data of two microbial fuel cells.
