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是相對濕度和溫度的超小型傳感器。它包括一個傳感元件和混合信號ASIC通過數(shù)字串行接口提供的測量信息。

該傳感元件由具有能夠檢測相對濕度變化的聚合物電介質(zhì)平面電容結(jié)構(gòu)組成，并且使用專用的過程制造。

在一個小的hts221頂孔帽柵格陣列是可用的（hlga）包保工作在溫度范圍從- 40°C + 120°C.
