Temperature & Humidity Sensor

SHT3x-DIS is the next generation of temperature and humidity sensors. The SHT3x-DIS has increased intelligence, reliability and improved accuracy specifications compared to its predecessor. Its functionality includes enhanced signal processing, two distinctive and user selectable I2C addresses and communication speeds of up to 1 MHz. The DFN package has a footprint of 2.5 x 2.5 mm2 while keeping a height of 0.9 mm. This allows for integration of the SHT3x-DIS into a great variety of applications. Additionally, the wide supply voltage range of 2.4 V to 5.5 V guarantees compatibility with diverse assembly situations.


1. Fully calibrated, linearized, and temperature compensated digital output
2. Wide supply voltage range, from 2.4 V to 5.5 V
3. I2C Interface with communication speeds up to 1MHz and two user selectable addresses
4. Typical accuracy of ±1.5 % RH and ± 0.2 °C for SHT35
5. Very fast start-up and measurement time
6. Tiny 8-Pin DFN package
