MLX90614是一款紅外非接觸溫度計。TO-39金屬封裝裏同時集成了紅外感應熱電堆探測器晶片和信號處理專用集成晶片。由於集成了低雜訊放大器、17位模數轉換器和強大的數位信號處理單元,使得高精度和高分辨度的溫度計得以實現。溫度計具備出廠校準化,有數位PWM和SMBus(系統管理匯流排)輸出模式。作為標準,配置為10位元的PWM輸出格式用於連續傳送溫度範圍為-20 ~ 120 °C的物體溫度,其解析度為0.14 °C。POR默認模式是SMBus輸出格式。
在應用設計中需要注意上述精度是當傳感器在熱平衡和等溫條件下才能保證和達到的。 (傳感器封裝裡沒有溫差)封裝內部的溫差會影響溫度計測量的精度,如下因素會造成溫差:傳感器背部的熱電子,傳感器背部或旁邊的加熱器/冷卻器,或當熱/冷物體靠近傳感器,不僅會加熱傳感元件,而且會加熱溫度計封裝。需要盡可能避免使用造成熱梯度的操作或是將傳感器和該環境隔離。
