3G era has arrived, a variety of high-speed wireless applications are changing the way people live. With the continuous improvement of wireless bandwidth, the public information model to grab a fundamental change taking place, communication is possible anytime, anywhere, 3G handsets will hit the stage caused by the convergence of information. 3G communication is given to the characteristics of the information age businesses generate large amounts of data, it will effectively an extension of the Internet business to the mobile communication field, according to Japanese NTTDoCoMo survey, 70% of the 3G business in the indoor environment. Similarly, the scene for the North American mobile phone use survey data also show that, with business development and continuous improvement of user consumption habits, nearly 30% of the business use occurred in the home area, and nearly 35% of the business use in companies, restaurants and other indoor environments.
P14 Femto-Thermo Capacitive Humidity- and Temperature Sensor Product The P14 Femto-Thermo is a miniaturized form of our successful P14 SMD Thermo. The favourable one chip solution consists of a capacitive humidity sensor, based upon the famous P14 sensor, together with a Pt1000- sensor, at the same time. The achieved outstanding accuracy due to optimal thermal coupling makes your application top of the edge in the industry. The intrinsic high chemical resistance of the P14 together with its very high dew point temperature and operating temperature clearly put this sensor clearly to best in class. Advantages • Application in dew point applications and humidity generators • Heat and measure fast • Heat and measure comfortably even under dewing conditions • Humidity sensor + Pt1000-element on one chip • Outstanding accuracy due to optimal thermal coupling • High resistance to various chemicals Dewing resistant – fast recovering time after dewing, also at very high dewpoint temperatures • High operating temperature • Linear characteristic curve • RoHs conform Technical Data Humidity Sensor: Capacitive Polymer Humidity Sensor Temperature Sensor: Pt1000 Ω DIN Kl.
