Abstract
As the industry and the society developing, the temperature bees more and more
important and a lot of products are sensitive to temperature. However,
temperaturemeasuring apparatus in the market now only can check and measure the
temperature of one point, at the same time, the temperature information is not real time
and the precision is low. It takes a great of troubles for the industry-controllers to make
decision .In this situation, design and implement one applicable system which can
watch measure and control the temperature and the measuring results is real time and
the precision is great is more essential. In order to meeting this application, this paper
talk about The Multiple-Point’s temperature Measuring System.
This system based on single chip puter, can inspect and control multiple
temperatures in real time. As a kind of high-accuracy digital net temperature sensor,
DS18 B20 can be used building a sensor net easily. It can also make the net simple and
reliable with it's special 1-wire interface .This paper introduces the application of
DS18B20 with single chip processor.
