Abstract

The Internet of Things technology is more and more widely used in industrial life, among which LORA technology is also becoming mature. However, the wireless sensor node cannot replace the battery frequently due to the limitation of the environment where it is placed, but it also requires the device to have a certain life length in the use environment. Based on the actual requirements, this paper proposes a system method of energy management and dynamic voltage regulation, which can reduce the power consumption of the module from the two aspects of software and hardware design respectively, to achieve the requirements of reducing the power consumption and improving the service life of the module. This article mainly describes how to reduce the power consumption in the hardware.
