Solar Powered Wireless Sensor Node
Wireless sensor nodes are popular solutions when it is difficult or impossible to run a mains supply to the sensor node. Often these sensors are located in places that also make it inconvenient to replace batteries regularly. In this case, harvesting local energy to power the node is desirable. There are different types of energy that can be harvested, the most popular is solar. Solar powered wireless sensor nodes are used in industrial controls, home and building automation, security and in agricultural systems.
