Retro Tech & Electronics | DIY Ultra Low Power Soil Moisture Monitor with an ESP32 using Arduino IDE @retrotechandelectronics | Uploaded April 2024 | Updated October 2024, 1 day ago.
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
