| Abstract: | The problem introduces AT89C52 monolithic machine and the DS18B20 figure temperature sensor-based multiple spot temperature measurement system mainly.AT89C52 single chip using the system were collected at various temperatures of the temperature, temperature display and alarm functions. It AT89C52 MCU-based control chip, digital temperature sensor DS18B20 the realization of multi-channel temperature detection, measurement accuracy can reach 0.5℃. The system uses LCD1602A liquid crystal display modules,LCD1602A as a display, the display of visual images to measure the temperature. AT89C52 single chip based on single-bus multi-point temperature measurement and control system with simple hardware components, multi-point temperature, easy reading, high-accuracy, wide temperature range, and other characteristics of the actual projects are widely used. |
