It’ s particularly important to control and detect the temperature promptly and exactly.It has designed a high precision temperature testing system in the base of lost control, which can inspect eight route temperature at one time and show each route of temperature by LCD. AT89C51is adopted as control core in this system. Its sensors for temperature is single bus digital DS18B20, sending temperature to LM041L LCD to display. When it operates normally, it ’ s temperature ranges from -55℃ to +125℃, the system has a good application prospect in the morden period when electronics industry developing rapidly.
