With the rapid development of microcomputer measurement and control technology and widely used, with the single chip processor as the core temperature gathering and control system of research and application to a large extent, improve the production control of the temperature level in the life. The water temperature control system adopts the ATMEL company produces the AT89S51 as the core control device to achieve the automatic control water temperature 30 degrees to 100 degrees, the temperature control system based on DS18B20 temperature sensor, photoelectric coupler MOC3041 and bidirectional thyristor constitute the main control circuit. The system can real-time temperature data storage and record according to temperature. Hardware control circuit mainly includes the AT89S51 minimum system, temperature measuring points, the clock circuit, section 8 of digital transistor display circuit. System program mainly includes the main program, read temperature subroutine, calculating temperature subroutine, button handler, section 8 of digital transistor display program and data storage and so on. Key words: single chip microcomputer AT89C52, DS18B20 temperature sensor, two-way thyristor BTA16-600 - b, 8 period of digital display circuit, transistor water tem
