A Design Scheme of Infrared Thermal Imager Based on MLX90640
By using the sensor MLX90640 and MCU GD32F103 as the core,and ILI9341 display screen,a non-contact fast temperature measurement portable infrared thermal imaging instrument is designed in this paper.The instrument realizes the data exchange between MCU and sensor through IIC interface,and transforms the obtained infrared temperature mea-surement value into gray level and RGB565 code,finally displays the image on TFT-LCD.It is proved that the application of the sensor MLX90640 in infrared thermal imaging technology,which has a good rapid temperature measurement ability when dealing with large traffic and dense personnel,and can measure the temperature of the current environment more ac-curately,and meet the needs of detecting hidden electronic products.
