基于单片机的多点温度检测系统设计与实现

The development of integrated circuits has greatly promoted the practical application of single-chip control circuits. Single-chip microcontrollers have characteristics such as small size, light weight, low cost, low power consumption, strong control functions, and fast processing speeds, making them widely used in measurement and control systems, intelligent instruments, electromechanical integration products, intelligent interfaces, and other fields. By using a single-chip microcontroller as the core, temperature sensors can be used to collect temperature data and process it accordingly. This system utilizes four DS18B20 temperature sensors to send the measured temperatures to the AT89C52 single-chip microcontroller, which then processes the data and sends it to a display unit for visualization. The system also allows for setting temperature limits and implementing alarms for each point, using the master-slave distributed system concept to achieve remote temperature control, thus creating a multi-point temperature detection system. Keywords: single-chip microcontroller, temperature sensor, multi-point temperature detection.
