"智能单片机家居防火防盗报警系统设计与实现"

Abstract: With the continuous progress of society and the development of science and technology and economy, people's living standards have been greatly improved, and people are paying more and more attention to personal safety, thereby placing new demands on fire and theft prevention measures. This design of an intelligent home control system includes indoor information intelligent monitoring, input and real-time display functions, and sound and light alarm functions. This paper utilizes a single-chip microcomputer combined with sensor technology to develop this fire and theft alarm system. This design uses the DYP-ME003 human infrared induction module, 18B20 temperature sensor, and MQ_2 smoke sensor to detect signals, which are then sent to the single-chip microcomputer for processing to achieve sound and light alarms. The system initializes the temperature and smoke concentration by pressing the button, and uses the LED display module to show the real-time temperature and smoke concentration. The system has a simple structure, stable performance, easy to use, low cost, and practical value. Keywords: fire and theft alarm, 18B20, MQ_2, DYP-ME003.
