+**<mark>NCIR</mark>** is a unit can measure body temperature or be applicated for movement detection which integrates **MLX90614** (an infrared thermometer designed for non-contact temperature sensing). The difference between it and the **[Thermal Unit](en/unit/thermal)** is mainly the NCIR Unit for surface single point temperature measurement, and the Thermal Unit for large area temperature measurement.
 
 The unit comunicates with M5Core with I2C. And It's I2C address is 0x5A.

 ## 描述
 
-**<mark>NCIR</mark>** 是一款内置了红外传感器 **MLX90614**，可以测量人体或者其他物体表面温度的 Unit 。它与 **Thermal Unit** 的区别，主要是 NCIR Unit 做表面单点温度测量，而Thermal Unit 做大面积范围的温度测量。
+**<mark>NCIR</mark>** 是一款内置了红外传感器 **MLX90614**，可以测量人体或者其他物体表面温度的 Unit 。它与 **[Thermal Unit](zh_CN/unit/thermal)** 的区别，主要是 NCIR Unit 做表面单点温度测量，而Thermal Unit 做大面积范围的温度测量。
 
 该 Unit 与 m5core 通过 IIC 通信，IIC 地址为 0x5A。
