Design of Data Transfer Module Based on STM32 in Monitoring System of Cold Chain Transportation

Based on the characteristics of centralized supervision, local distribution and overall mobility, a cold chain transportation monitoring system is designed. In this system, STM32 microprocessor is used as the main controller of the data transfer module, wireless module based on SX1212 chip is utilized to Ad Hoc network, GPRS module is utilized to upload data to server. This system can monitor temperature, humidity, battery capacity, and route information, to ensure smooth and safe operation of Cold Chain Transportation. The system is stably, safe, as well as energy saving.
