Method and system for remote monitoring and control utilizing radio frequency devices

摘要

A method and device for remote monitoring of conditions and control of objects that includes an antenna configured to receive and send radio frequency signals, a receiver configured to receive the radio frequency signal and to operate from the power of the received radio frequency signals, a microcontroller coupled to the receiver and configured to respond to the radio frequency signals to report a condition and to control an associated object. The microcontroller may be powered by the radio frequency signal or may receive power from a stored energy source or an external power source.
