Design of temperature controller based on MCU
Abstract: in order to perform some of the monitoring of the temperature of the indoor environment, this article is designed to AT89C2051 single-chip microcomputer as control core temperature controller. The design mainly includes the temperature acquisition, control, display and alarm and temperature threshold setting of several modules. The controller mainly through the temperature sensor on the indoor temperature monitoring, and the result of measurement is real-time single chip AT89C2051, single-chip processing in the digital tube display, if temperature exceeds the set value is controlled by microcomputer relay action, in order to control the temperature regulating equipment. This design not only includes hardware circuit design, including software design process and its implementation. The test results show that, the design of stable operation, high measuring accuracy, temperature range, good real-time performance, simple operation, low cost.
