I was looking for a solution for measuring the moisture content of the plants soil in our house, however I wanted something battery powered and simple. A low power design would have to be though up from the start. Everything would be built around the lilygo T5 epaper display using the GXEPD2 library.

A future project to design and print a custom enclosure will be posted here
