Temperature Control By Single Chip Microcomputer

Temperature control by single chip microcomputer is a control method frequently used in industrial production. Since the first batch of single chip microcomputer was introduced by Intel in 1976, the technology of single chip microcomputer entered a period of rapid development in the 1980s. MCU is mainly used for control. Its application field covers all walks of life, ranging from space shuttle to refrigerator and color TV in daily life. The temperature control system with single chip microcomputer as the core also came into being. The traditional temperature collection circuit is quite complex, which requires a series of work such as temperature collection, signal amplification, filtering, AD conversion and so on to get the digital quantity of temperature. Besides, this mode is not only complicated in circuit and has many components, but also unsatisfactory in linearity and accuracy and weak in anti-interference ability. The commonly used temperature sensor chips not only have low power consumption and high accuracy, but also have better linear performance than the traditional temperature sensor chips. The most important point is that they are easy to use. Let's discuss and study a temperature control system based on temperature sensor with single chip microcomputer as the core.
