The high -precision 1 -wire temperature sensor DS18B20 was used to detected the temperature in the design, and the AT89C51 was used as a control unit. The temperature data was sent by RS-485 transceiver and transmitted via RS-485 bus. The software which was used for serial communication and temperature display was designed by VC++ 6.0, so the temperature data was displayed on PC to achieve the real-time remote detecting of temperature data. The system with simple equipment is inexpensive and suitable for in-dustrial.
