00026 //! Library for the Sensirion SHT3X-ARP Analog Humidity & Temperature Sensor.
00027 /*!
00028  SHT3x-ARP is the next generation of Sensirion’s temperature and humidity sensors. 
00029  It builds on a new CMOSens sensor chip that is at the heart of Sensirion's new humidity and temperature platform. 
00030  The SHT3x-ARP has increased intelligence, reliability and improved accuracy specifications compared to its predecessor. 
00031  Its functionality includes enhanced signal processing, temperature and humidity can be read out at different pins. 
00032  The DFN package has a footprint of 2.5 x 2.5 mm while keeping a height of 0.9 mm. 
00033  This allows for integration of the SHT3x-ARP into a great variety of applications. 
00034  Additionally, the wide supply voltage range of 2.4 to 5.5 V guarantees compatibility with diverse assembly situations. 
00035  All in all, the SHT3x-ARP incorporates 15 years of knowledge of Sensirion, the leader in the humidity sensor industry.
