Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a wireless temperature and humidity sensor. Background technique [0002] The cold chain system refers to the system engineering that requires strict control of temperature and humidity in all links during the transportation or storage of certain special foods and medicines. With the rapid development of my country's cold chain logistics industry, the problem of insufficient temperature and humidity monitoring has led to frequent incidents of food and drug deterioration, which seriously threatens people's health. Therefore, the development of a complete set of cold chain equipment has become very urgent. [0003] The traditional temperature and humidity sensor can only be used as a transfer station when processing data. It uploads the received data to the host computer, and the host computer processes the data. When there are too many nodes, this method of uploading all data has...
