Description
Description
PCB for an ESP32-based LoRaWAN controller unit that operates up to eight SMT100 soil moisture sensors connected via RS485.
Relying on this design, we have assembled multiple controller units and deployed them on agricultural land in southwest Germany as part of the 5G-PreCiSe Project.
The whole project is documented on GitHub.
