Implementation of an energy harvesting powered orientation estimation sensor

The Internet of Things and Wireless Sensor Nodes are spreading into more and more homes and offices. Current wireless sensor systems rely on the use of batteries. Since batteries are made from scarce resources and have to be exchanged regularly their use is not optimal. To avoid these limitations energy harvesting is a possible alternative. Currently most energy harvesting based sensor nodes use simple low energy sensors. To expand the possibility of energy harvesting this paper presents a sensor node using a geomagnetic sensor, which normally is used in battery or mains powered devices.
