The prototype system is optimized to transmit 20mW over 20cm distance (18cm-deep soil with a 2cm air gap above the ground) to energize an underground soil moisture sensor.

CRITERIA 1D is a one-dimensional agro-hydrological model. It includes soil water fluxes, crop development and crop water needs, a GIS interface (CRITERIA GEO) for geographical simulations and tools to ...

I reworked that minimalistic version into a library and I added a number of Arduino examples to help you get started. Effort has been taken to keep the code, variables and function ... only the ...
