Intelligent logistics monitoring microsystem based on STM32

A intelligent logistics monitoring microsystem has been designed based on STM32F103T8, which is high ability, low power consumption and low cost. The radio frequency (RF) chip CC1101, the acceleration sensor BMA280 and the temperature and humidity sensor HTU21D are selected to acquire the corresponding data for the intelligent logistics microsystem, which are ultra-low power consumption and ultra-small size. Moreover, in order to further reduce power consumption, the interrupt mode is adopted in the data acquisition module and the sleep mode is used in the MCU module in the software control. On the other hand, in order to further optimize the performance of miniaturization, the SWD (Serial Wire Debug) protocol is used. Meanwhile, the system will alarm the transportation officer once the acquired data met or exceed the threshold, which will help him to take corresponding measures timely, thus reducing the risk of occurrence effectively.
