Design of a practical computer multi-point temperature detection system [Copy link]

A practical new computer temperature acquisition system with 89C52 as the core is designed. It uses J-type thermocouple as the temperature measuring element and uses the integrated current temperature sensor AD590 to achieve effective compensation of the thermocouple cold end temperature, thereby improving the accuracy, stability and anti-interference performance of the system. The system mainly studies the component selection and circuit design based on engineering practice. While giving the core hardware circuit, an expandable circuit that can collect and process multi-channel data and realize the alarm function is proposed. Low-cost, long-distance transmission temperature patrol detection is realized.
