The company is launching its new generation of humidity and temperature sensors. The SHT21 conforms to the current trend of saving space and re-ducing energy consumption. The sensor incorporates the existing strengths of the successful SHT11 while enhancing and improving them. For instance, the sensor not only features long-term stability, full calibration and a digital interface, but also supports additional communication modes, including analog modes. In addition, sensor reliability and performance have been boosted by using advanced semiconductor technology. The QFN components are resin encapsulated to minimize the sensor dimensions. With a 3 x 3mm footprint and a height of 1.1mm, the sensor fulfills practical every wish with regard to the compactness of integrated sensors. Encapsulation of the semiconductor chip also provides reliable protection against ambient conditions and thus increases the stability of the sen-sor. The sensor can be processed in a reflow oven. It is correspondingly suitable for use in mass production.
