And with the develop- ment of computer control system, the efficiency of scientific research、the industry and the agriculture production has get a big enhancement. This design is a relay automatic water temperature control system based on AT89C52. It has the real time display, the temperature survey、hypothesis and can carry on the adjustme- nt according to the setting value. The control algorithm based on the digital PID algorithm. The temperature survey scope from 0~+100 ℃, the temperature control scope for 20℃~90℃, the survey precision for 1℃, is smaller than over 5%. The experimental result indicated that this system can control the water temperature well, satisfies our request.
