Abstract
An apparatus and method for detecting a condition within a wireless charging field are described. In one implementation, an apparatus comprises a wireless power receiver configured to receive wireless charging power from a wireless power charging transmitter. The apparatus further comprises a first sensor circuit that is at least partially disposed within a ground surface, the first sensor being operationally coupled to and configured to be charged or powered by the wireless power receiver. The first sensor is further configured to detect the condition.
