ULP Wireless Temperature Sensor With Energy Harvesting

Ultra low power (ULP) wireless temperature sensors can be designed from a combination of harvested energy and a rechargeable battery. The diagram depicted here show an example of an ULP wireless sensor using Thermo Electric Generators (TEG). These are devices which convert heat (temperature differences) directly into electrical energy, using a phenomenon called the "Seebeck effect".

Generic Energy Harvesting Sensor

Industrial wireless sensor networks powered by harvested energy can be used to perform a variety of useful functions including factory automation, measurement, and control. Today, several system vendors are developing and promoting self-powered wireless monitoring and control systems for sustainable buildings, using self-powered wireless monitoring and control system standards using energy harvesting technology. Energy-harvested sensor nodes use low-cost integrated circuits to perform sensing, signal processing, communication and data collection functions, and also include a low-power wireless communications interface.
