Energy harvesting algorithms for wireless multi-sensor gas platform

Air quality control is a monitoring task of high priority in the scope of Smart City and Smart Home applications. In fact, a number of sensors are required to successfully detect the leaks of various gases and their different concentrations. Using wireless sensor platform for these purpose it's necessary to think a lot about appropriate power sources and power management. In this work, we present autonomous multi-sensor wireless platform power supply algorithms. The platform uses alternative power sources (solar panel and wind generator) as main power supply and lithium battery as reserve one. These power supply components are managed to maintain the most efficient using of power sources during whole working cycle.
