【正文】 ve to consider the factors with temperature. Temperature for industrial so important, thus promoting the development of the temperature sensor. Temperature sensor development Major general through three sensor development phase: analog integrated temperature sensor. The sensor is taken with silicon semiconductor integrated workmanship, therefore also called silicon sensor or monolithic integrated temperature sensor. Such sensing instruments have single function (only measuring temperature), temperature measurement error is smaller, price low, fast response, the transmission distance, small volume, microconsumption electronic etc, suitable for long distance measurement temperature, temperature control, do not need to undertake nonlinear calibration, peripheral circuit is simple. It is currently the most mon application at home and abroad, an integrated sensor。 Single point and more temperature sensor The development trend of the temperature sensor. In the 21st century, the temperature sensor is headed in high precision, multifunction, bus, standardization, high reliability and safety, development of virtual sensor and work sensor, research monolithic temperature measuring system and other hightech direction develop rapidly. Sensors in the application temperature controlling system. Current market exists mainly single point and more two temperature measurement. For single point temperature foundment instrument, mainly adopts the traditional analog integrated temperature sensor, which heat resistance, thermocouple sensors measuring accuracy, high measurement range, and got the general application. This product is temperature measuring range ℃ ~ 200 mostly between 800 ℃ , resolution 12th, and least distinguishable temperature in ~ between. Cabin LED display module, shows ranging from 4 to 16. Some instruments also has memory function, can store several hundred to a few thousand sets of data. This instrument can be very good meet a single user singlepoint measurement needs. More temperature measurement, relative and single point measurement precision has certain gap, although realized the multichannel temperature measurement and control, but the price is expensive. In view of the present market situation, proposed this topic can satisfy requirements, scalable and costeffective singlechip multichannel temperature measuring system. Through the first temperature sensor DS18B20 acquisition, and then through the C51 SCM processing and displayed on the digital tube, can be collected indoor or a greenhouse around in different locations of the temperature, with four digital tube to display. The first digital pipe display acquisition is which way, which channel. Three digital pipe display after the acquisition channel by temperature, accurate to degrees. 2. The system realized and related technologies system is realized By the whole control system for core AT89C51, using four ways of temperature sensor DS18B20 in production site for distribution area of four different temperature measur
