Embedding Application Note for the digital SHT2xS humidity and temperature sensor series integrates multi-functionality on a small footprint. Due to the underlying physics of the highly integrated on-chip CMOS circuitry the supply voltage of the SHT2xS is restricted to 2.2 - 3.6V. This application note provides sample schemes for embedding SHT2xS sensors with I2C-bus, PWM interface and SDM interface into 5V power supply environment
