The scope of this paper is to demonstrate how the temperature difference between indoor and outdoor can be harvested to generate electricity for powering wireless sensor nodes (WSNs). Monitoring and controlling of processes by numerous WSNs are being developed but the power supply is still a challenge. Replacing the batteries of the WSNs which are not easy to reach due to their positions can reveal the importance of energy harvesting for powering them. In this research saving energy by designing ultra low power consumption hardware and obtaining energy from the environment are two major objectives to enhance the life time of WSNs. The main idea is to offer a way to supply the WSNs directly from the accessible slight heat flow where is available in a building. The advanced technology brings this opportunity to design the ultra low power devices that presents reduction of power consumption significantly, and the slight resources can be harvested directly to power these devices.
