In this post you will see a quick introduction to the revered POWERCAST P1110B RF Power Harvester Module!
The P1110B is a compact 915 MHz RF Energy Harvester for small/wearable Electronics.
Energy harvesting is the process for collecting ambient energy in the forms of light, motion, vibration, heat, radio waves, etc. and converting it to electricity! In recent years, this clever idea has become increasingly attractive, and a number of methods to produce electricity from surrounding energy sources have been developed. Nowadays, possible applications can be found in IoT devices, sensor networks, and even military equipments.
POWERCAST P1110B
The P1110B is a module that harvests background radio-frequency (RF) signals and converts them to a DC voltage. The receiver can reach 70% conversion efficiency in the 902-928 MHz frequency band, although the module can still harvest energy outside this band. Output power can be used to charge a battery directly rather than being stored in a capacitor.
Note that the P1110B converts RF energy to DC and provides the energy to the attached storage element. When an adjustable voltage threshold on the storage element is achieved, it automatically disables charging. A microprocessor can be used to obtain data from the component for improving overall system operation.
