People pay more attention to personal safety, thus they put forward new requirements for the fire and security measures. In this design ,the intelligent family- house control system includes this function : indoor information intelligent monitoring , the input and real-time display ,sound and light alarm, and so on .The design is a fire and security system, which combines sensor technology with microcontroller. This design adopts the DYP-ME003 human body infrared sensor module,18b20 temperature sensor and MQ_2 smoke sensor to detection signal. These sensor send the signals to microcontroller.The microcontroller process these signal and drive alarm circuit to achieve sound and light alarm .The fir temperature and smoke concentration are initialized in this system.,and are displayed in the LED display .The system has the advantages of simple structure ,stable performance ,conventional operation ,low price ,and has a certain practical value .
