Abstract: Multiple subterranean probes at an area of land detect soil conditions and wirelessly transmit soil condition information to a service provider's backend server or to a technician's hand-held wireless device. The server provides multiple user interface screens of a customer application that display soil condition information and irrigation's system status. Local micro weather stations may determine and wirelessly transmit weather condition information to the server. An installer may use the customer application to determine that received signal strength at a given probe is weak and should thus be relocated, or to determine refined location information corresponding to the probe. Historical soil condition information and artificial intelligence may predict soil conditions where a previously installed probe has been moved or quit working. Probes' housings seal internal electronics, including soil condition sensors, wireless communication modules, processors, and memory.
