If the emergence of microcomputers has made modern scientific research achieve a qualitative leap, then the emergence of single-chip microcomputer technology has brought a new revolution to the modern industrial control and measurement field. At present, single-chip microcomputers are developing towards high performance and multiple varieties. The trend will be further development in several aspects such as CMOSization, low power consumption, small volume, large capacity, high performance, low price and built-in peripheral circuits.This article mainly introduces the design of a smart home control system based on a single-chip microcomputer. The system uses the STC89C52 single-chip microcomputer as the control core, uses the DS18B20 temperature sensor to collect temperature, uses the DHT11 temperature and humidity sensor to collect humidity, uses the MQ-2 smoke sensor to collect smoke concentration, and uses a photoresistor to collect light intensity. , using HC-SR501 human body infrared sensor to detect whether there is anyone, using LCD1602 liquid crystal display to display the collected data, using LED lights to simulate light control, using DC motor to simulate fan control, using relay to simulate curtain control, using buzzer to perform Alarm, use independent buttons for manual control, and use Bluetooth module for wireless control. The system can realize real-time monitoring of indoor temperature, humidity, smoke concentration, and light intensity. When the temperature, humidity, smoke concentration, and light intensity exceed the set threshold, the system will automatically alarm and send the alarm information to the mobile phone APP through the Bluetooth module. . At the same time, the system can also control lights, fans, and curtains through the mobile APP or independent buttons. The system has the advantages of simple structure, low cost, high reliability and strong practicability.**Key words:** single chip microcomputer; smart home; control system; sensor; bluetooth# 目录## 第1章绪论1.1 研究背景及意义......1 1.2 国内外研究现状......1 1.3 本文主要研究内容......2 ## 第2章系统总体设计2.1 系统设计目标......3 2.2 系统设计方案......3 2.3 系统硬件选型......4 2.3.1 单片机选型......4 2.3.2 温度传感器选型
