This paper attempts to develop a non-contact temperature measurement tool with high accuracy and fast speed. Therefore, an infrared temperature measurement system was designed with STC12C5A as the core. In the system, the STC12C5A controls infrared temperature sensor MLX90614 to obtain surface temperature of the target, and displays the processed temperature data on the LCD1602. If the displayed data exceeds the pre-set range, an alarm will be released by a buzzer in the alarm module. Then, the measuring accuracy and measurement distance of the system were verified through system tests. The results show that the proposed system is more accurate than the reference sensor; the optimal measurement distance is less than 2cm, for the corresponding mean error is below 0.88%. The proposed system clearly outperforms the traditional contact measurement method in speed, accuracy and safety and enjoys a strong potential of application.
