The HTS221 is an ultra compact sensor for relative humidity and temperature. It includes a sensing element and a mixed signal ASIC to provide the measurement information through digital serial interfaces.

The sensing element consists of a polymer dielectric planar capacitor structure capable of detecting relative humidity variations and is manufactured using a dedicated ST process.

The HTS221 is available in a small top-holed cap land grid array (HLGA) package guaranteed to operate over a temperature range from -40 °C to +120 °C.

hts221是相对湿度和温度的超小型传感器。它包括一个传感元件和混合信号ASIC通过数字串行接口提供的测量信息。

该传感元件由具有能够检测相对湿度变化的聚合物电介质平面电容结构组成，并且使用专用的过程制造。

在一个小的hts221顶孔帽栅格阵列是可用的（hlga）包保工作在温度范围从- 40°C + 120°C.
