"基于单片机的多点温度检测系统实践与应用"

The development of integrated circuits has greatly promoted the practical application of microcontroller-based control circuits. Microcontrollers, with their small size, light weight, affordable price, low power consumption, strong control functions, and fast processing speeds, have found widespread applications in measurement and control systems, intelligent instruments, electromechanical integration products, intelligent interfaces, and more. By using a microcontroller as the core, temperature sensors can be utilized for temperature data acquisition and processing. This system uses four DS18B20 temperature sensors to send temperature readings to the AT89C52 microcontroller, which processes the data and sends it to the display unit for visualization. The microcontroller is used to set temperature upper and lower limits, monitor and control the temperatures at different points, and implement temperature alarms. By employing a master-slave distributed system architecture, remote temperature control is achieved, creating a multi-point temperature detection system. Keywords: microcontroller, temperature sensor, multi-point temperature detection.
