16-07-2015 | Mouser Electronics | Test & Measurement

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.
