Abstract In order to better solve the problem of temperature and humidity detection in the severe cold districts，a temperature and humidity detection system that is based on the single-bus technology has been designed. The overall design scheme of the system and hardware design such as the single-bus temperature and humidity detection circuit，communication circuit，as well as system software design and flow are described. Through the comparison of the temperature and humidity measuring results before and after the compensation，it is indicated that the system can meet relatively high requirements of the temperature and humidity.
