Nowadays, there is an increasing demand for long‐distance, wide‐distributed, and low-speed unmanned detection equipment in the market. However, most unmanned monitoring equipment is powered by batteries, and often faces the dilemma that the batteries are exhausted but no one maintains them. In order to solve this problem, a distributed battery detection system based on micro‐power wireless communication is designed. The system consists of three parts: voltage measurement module, micro-power wireless ad hoc network and terminal display part. Using the idea of modularization, the terminal hardware circuit is designed and realized. The acquisition module of the voltage measurement module mainly realizes the acquisition and reporting of the battery voltage, and receives the information sent by the terminal. This is of great significance to promoting the development of my country's unmanned testing equipment market, bringing changes to urban management and public services, and promoting environmental protection and sustainable development.
