Energy consumption is the biggest issue in wireless sensor network and mobile devices. In this proposed model, available radio signals in the region are converted to DC supply and stored in a battery. This power RF harvesting conversion is done by P2110. From the stored energy, controllers which operate at 5V can be powered. Microcontroller measures environmental parameter and transmits it to the co-ordinator. So that without additional batteries or any power source devices on 5V range can be operated.
