Facilities Environment Temperature Measurement Circuit Design
Abstract: Facilities for measuring the environment temperature is expected, or absolutely necessary. The paper introduced a temperature sensor AD590 features and characteristics of the principle of AD590, and a brief introduction to the ADC0809, SCM AT 89C2051, give a method of the design of the thermometer which is based on the temperature sensor AD590. This thermometer is mainly used to measure the temperature of the environment. With high measurement accuracy, the error small, easy to carry, etc.
