Bluetooth Low Energy Beacon Powered by the Temperature Difference

Bluetooth low energy beacons are active transmitters that send a radio signal at set intervals. Most powered by small batteries. The problem with systems based on such devices is the need to periodically replace chemical cells. This especially tedious when large number of used. maintenance system causes several serious problems related high cost new batteries and their replacement, time-consuming service environmental pollution. A solution these use power supply supported photovoltaic panels. Their obvious drawback place them in good lighting conditions. To overcome this disadvantage, source gathers due Peltier effect proposed paper. Since temperature difference between two surfaces can be found almost every environment, authors analyzed efficiency kind context powering beacons. In order justify idea, multitude measurements simulations was performed. demand beacon measured various modes operation. module examined different loads differences. On basis gathered data, conditioning defined for given sufficient beacon. Finally, model device developed. elaborated eliminates makes maintenance-free.
