文摘

The monitoring system is controlled via embedded device S3C6410 microprocessor. High-precision processing circuit is proposed for physical signal conversion. The data correction algorithm is designed based on least-square method. The maximum error of the data correction model is higher than ±0.05 °C obviously.
