Based on MCU AT89S52 Temperature Control System

The water temperature as the main control objectives, the real-time temperature control system is designed, in this system MCU AT89S52 is used as the core control device, integrated temperature sensor AD590 because of good linearity and high sensitivity, and A / D converter with high resolution and low noise are used for temperature acquisition,the system has achieved the temperature 40 ~ 90°C automatic control, it has set temperature display, real-time display of the current temperature function, after the actual operation shows that the system is better able to control the temperature.
