According to analysis and statistics, nearly 30% of the fires are caused by electrical circuit faults, ranking first in all types of fire accidents. And electrical wiring failures are one of the main causes of most major fires. Such fire accidents not only cause casualties and economic and property losses, but also may cause large-scale paralysis of the power system in the fire site and nearby areas, bringing great inconvenience to the production and life of residents.

LoRa technology occupies an important position in the development of the Internet of Things. Because of its ease of construction and deployment, it has become a commonly used Internet of Things dedicated network communication technology. In recent years, due to the maturity of LoRa technology in the leading position, as well as the characteristics of long transmission distance, low power consumption and strong anti-interference, LoRa modules are widely used

Powering wireless Industrial Internet of Things (IIoT) sensors for applications such as machine condition monitoring is challenging. Sensors must be compact, robust, easy to deploy, inexpensive, and work reliably for long periods of time with little or no maintenance. The effects of sensor failure range from loss of vital data about machine condition to costly repairs to catastrophic failure of a system or production line.
