Measuring and Fuzzy-PID Controlling of Infrared Earth Sensor Temperature Based on P89C51 Microcontroller

One temperature measuring and controlling system for infrared earth sensor was designed based on P89C51 microcontroller, which adopted the segmentation modeling method, fuzzy-PID control algorithm. The system implemented the function of measuring and controlling the infrared earth sensor temperature, with the characteristics of high temperature collecting resolution, fast and accurate temperature controlling result.
