Wireless Data Acquisition Instrument for Roof Pressure Based on STM32

In view of problems of heavy workload and low efficiency in the measurement of roof pressure in coal mine,a wireless data acquisition instrument was designed based on STM32. Some aspects of this instrument were introduced emphatically, such as the structure, hardware design and software design. The data acquisition instrument collected data through wireless communication mode, reduced the workload of cable laying and maintenance effectively, and improved work efficiency greatly.
