Provided is a wireless self-check temperature and humidity primary tobacco maintenance detecting method. Temperature information, humidity information and bar code information detected by a wireless self-check temperature and humidity collector are transmitted to a signal receiving device, the signal receiving device transmits the temperature information, the humidity information and the bar code information to an internet data server through an IP network, the temperature information, the humidity information and the bar code information are transmitted to an intelligent data processing system, the processed temperature information, the processed humidity information and the processed bar code information are transmitted to a terminal server monitoring management platform, storing, monitoring, displaying and early warning are conducted on the temperature information, the humidity information and the bar code information through a computer software technology, and data of the terminal server monitoring management platform are skimmed remotely through a public network. The method achieves remote temperature and humidity detection of large-scale tobacco stacks, mildewing and carbonizing of tobacco leaves are reduced and prevented further, and spontaneous combustion of the tobacco stacks is effectively eliminated.
