An automatic switch for power consumption reduction based on the technology of Internet of Things

Internet of Things (IoT) has become a popular issue in academic research. The technology of Wireless Sensing Network can fully implement the concept of IoT. A WSN uses less expensive sensors to automatically monitor environmental factors and to transmit sensing data. Therefore, the cost of manually collecting sensing data can be largely reduced. WSNs are often deployed to an outdoor environment where power sources are limited. Moreover, the sampling cycle plays an important role in WSNs, and it deeply affects the accuracy of data analysis. This research purposes to add an automatic switch capable of adjusting sampling intervals to increase the flexibility of WSNs. Researchers can thus reduce the power consumption of WSNs by controlling the power supply of micro wireless devices and improve the quality of monitoring data by controlling the sampling cycle through a computer or a smartphone. Based on the simulation results, it can successfully reduce 54% of power use.
