Ultra-compact sensor for relative humidity and temperature applications

Aimed at relative humidity and temperature applications, the ultra compact STMicroelectronics HTS221 capacitive digital sensor is now available from Mouser stock. The device 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 -40C to +120C. Applications include air conditioning, heating and ventilation, air humidifiers, refrigerators, wearable devices, smart home and industrial automation.
