Abstract
We designed a temperature and humidity remote system to monitor the vaccine enviroment in the cold chain logistics and low temperature storage stage.Embedded controller STM32F103VCT6 is utilized to process the temperature and humidity signals from the sensor STH75.It communicates with the host server via the module GPRS DTU module SIM900A so that the remote monitor can be implemented.The system is applied and the running instance show that the system conforms to the requirements, which indicates that the design is reasonable and effective.
