ABSTRACT
The intermediate control module is composed of the nRF905 wireless transmission receiver, single-chip microcomputer and voice alarm control circuit. The nRF905 wireless communication receiver receives the temperature and humidity data sent by the acquisition module. The data after the single-chip microcomputer processing are sent to the PC to realize human-computer interaction through a serial communication. When the temperature and humidity transfinite, voice control circuit alarm (Li Qiang 2013).
