Experimental study for Infrared Temperature Measurement System

摘要

Infrared temperature measurement system is designed, Based on C51 microcontroller and infrared temperature sensor. The experimental study is executed for the character of designed system, and the results show as follows: for the range of 2.5-15cm, the error of measurement error is very small, less than 1°C; but in between 20-27cm, the error increased gradually. Overall the infrared thermometer ace achieve stable measurement with high precision and can be widely used in families, hospitals, schools, etc., and has good popularization and application prospect.
