Design of environmental quality monitoring system based on self-powered wireless wensor network

In order to accurately real time monitor the environmental quality for the specific area, and solve the problem of interruption of traditional wireless sensor network because the battery is not durable and can not be updated in time, we design a wireless environment quality monitoring system with self-powered multi-sensor. In this system, the network node is powered by solar photovoltaic panels, and the maximum power point tracking control algorithm is optimized and improved. It solves the problem of abnormal work of sensor nodes caused by not charging the battery in time, and realizes the unattended real-time monitoring of the environmental quality. Besides, data fusion of the multi-node sensor is performed by using the data fusion algorithm. The experimental results demonstrate that the test data of our designed system agree well with the environmental quality data released.
