Low-power wireless sensor design for LoRa-based distributed energy harvesting system

Abstract

With the development of electronic power technology, distributed clean energy harvesting is widely concerned, in the process of distributed energy harvesting, the process of monitoring energy harvesting equipment does not need to transmit a large amount of data to the host device, a small amount of status information can meet the purpose of monitoring, so in the wireless sensor network energy consumption is an important issue to be considered. It is very energy efficient, can transmit wireless data over long distances, and supports mesh networking. In the process of distributed energy harvesting, the wireless sensor network composed of LoRa can effectively monitor the environmental information and wireless energy harvesting system, and the battery requirement is very low, and the data can be distributed with very little power consumption, which can be used in harsh environment and remote mountainous areas. In this paper, the composition of the distributed energy harvesting system is discussed first, then the energy situation of LoRa in low-power wireless energy transmission is analyzed, and finally the wireless low-power sensor network is tested.
