"基于单片机的多点温度检测系统设计与实现"

Abstract: The development of integrated circuits has greatly promoted the practical application of microcontroller control circuits. Microcontrollers have features such as small size, light weight, low cost, low power consumption, strong control functions, and fast operation speed, making them widely used in measurement and control systems, smart meters, mechatronics integrated products, and smart interfaces. With the microcontroller as the core, temperature sensors can be used to achieve temperature acquisition and corresponding processing. In this system, four temperature sensors DS18B20 are used to send the measured temperature to the AT89C52 microcontroller, and then the microcontroller processes and sends it to the display unit for display. The system uses the microcontroller to set the upper and lower temperature limits and control the temperature measurement and control alarms for each point. By using the master-slave distributed thinking, remote control of temperature is realized, forming a multi-point temperature testing system. Keywords: microcontroller, temperature sensor, multi-point temperature testing.
