The researchers developed a thermoelectric harvester (TEH) prototype, an autonomous energy generator for low power supplies. This thermoelectric harvester is a constant, compact, cheap, capable of providing the energy consumption of the wireless sensors for a long time as a replacement for battery use. The energy source is the gradient that always exists between the pipe and the ambient air temperature. This gradient is converted into electrical energy using a thermoelectric converter. Generators, based on THE, are environmentally friendly, use renewable energy, and do not include gases and / or moving parts. Thermal and electrical optimization was performed. Physical and mathematical models were developed. Simulations and measurements were conducted on various sites for a year.
