The Grove-12C high-precision temperature and humidity sensor (SHT35) is based on the SHT3x-DIS. This is a new generation of temperature and humidity sensors from the Swiss sensor manufacturer Sensirion. It is built on the new CMOSens® sensor chip. This chip is the core of Sensirion's new humidity and temperature platform. Compared with its predecessor, SHT3x-DIS has higher intelligence, reliability and higher accuracy specifications (temperature error ± 0.1 °C, humidity error ± 1.5 %RH). Its functions include enhanced signal processing, two unique and user-selectable 12C addresses, and a communication speed of up to 1MHz.
