摘要
本系统以AT89C51单片机系统为控制核心,用线性度好、灵敏度高的集成温度传感器AD590及分辨率 高、噪声低的A/D转换器进行温度采集,采用线性数字校正和数字滤波技术,增强系统的灵敏度和抗干扰能力。
The system use a microcontroller AT89C51 to control temperature with good linearity, high sensitivity integrate temperature sensor AD590 and high resolution , low noise A/D transfer to sample. And it used nonlinear digital rectifier and digital filter to make sensitivity of system higher and to make anti-interference capacity of system stronger.
