The invention provides a method and device for monitoring intelligent homes based on short messages, and relates to the communication field of Internet of Things. The method includes the steps that firstly, a user carries out one-key monitoring through a mobile phone terminal to select functions that the user wants to realize; secondly, a TC35 short message communication module receives information and then transmits the information to a PC machine, and the PC machine processes the information and transmits commands to a CY7C68013A data collection module; then, after the CY7C68013A data collection module receives the commands, household appliances, sensors and the like execute the commands, wherein the household appliances, the sensors and the like are connected to the back end of the CY7C68013A data collection module; finally, if the commands require that the information needs to be returned, the household appliances, the sensors and the like can execute the above procedures in reverse, and information data needed by the user can return to the mobile phone terminal of the user. The method and device can realize home intelligence, and the functions of remote switch-on and switch-off, reading of indoor temperature and humidity, automatic flower watering, gas leakage warning, fire warning, anti-theft warning and the like can be achieved.
