Aiming at the current needs for intelligent control of household appliances, this paper presents a technical scheme for realizing intelligent control and security control of household appliances by using the model STC89C52 of microcontroller as main control chip. This system uses GSM mobile SMS network for remote communication, combined with sensors, relays and other hardware control circuits, achieving a kind of smart home system with remote control function. According to the test feedback, this system is cost-effective, safe and reliable, meeting the needs of home control.
