Abstract
A network sensor system and method for using the same are disclosed herein. In one embodiment, the network sensor system comprises: a radio-frequency (RF) emitter; a first sensor tag including a transmitter, an energy harvesting unit operable to convert incident RF energy to direct current (DC) including RF energy from the RF emitter and RF energy from one or more ambient sources, a storage unit operable to store recovered DC power, one or more sensors for sensing and logging data, a controller coupled to the energy harvesting and storage units, the one or more sensors and the transmitter, to communicate data in the form of a Bluetooth Low Energy (BLE) advertising packet using energy previously harvested and stored by the energy harvesting and storage unit; and a first device to receive the BLE advertising packet.
