SHT30-DIS pdf
Datasheet SHT3x-DIS
Humidity and Temperature Sensor
Fully calibrated, linearized, and temperature
compensated digital output
Wide supply voltage range, from 2.4 V to 5.5 V
I2C Interface with communication speeds up to 1
MHz and two user selectable addresses
Typical accuracy of 1.5 %RH and 0.1 °C for
SHT35
Very fast start-up and measurement time
Tiny 8-Pin DFN package
Product Summary
SHT3x-DIS is the next generation of Sensirion’s
temperature and humidity sensors. It builds on a new
CMOSens® sensor chip that is at the heart of Sensirion’s
new humidity and temperature platform. 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. All in all, the SHT3x-DIS incorporates 15
years of knowledge of Sensirion, the leader in the
humidity sensor industry.
Benefits of Sensirion’s CMOSens® Technology

1 For definition of typical and maximum accuracy tolerance, please refer to the document “Sensirion Humidity Sensor Specification Statement”.
2 The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurements at the stated repeatability and at constant ambient conditions. It
is a measure for the noise on the physical sensor output. Different measurement modes allow for high/medium/low repeatability.
3 Specified range refers to the range for which the humidity or temperature sensor specification is guaranteed.
4 For details about recommended humidity and temperature operating range, please refer to section 1.1.
5 Time for achieving 63% of a humidity step function, valid at 25°C and 1m/s airflow. Humidity response time in the application depends on the design-in of the sensor.
6 With activated ART function (see section 4.7) the response time can be improved by a factor of 2.
7 Typical value for operation in normal RH/T operating range, see section 1.1. Maximum value is < 0.5 %RH/yr. Higher drift values might occur due to contaminant
environments with vaporized solvents, out-gassing tapes, adhesives, packaging materials, etc. For more details please refer to Handling Instructions.
8 Temperature response times strongly depend on the type of heat exchange, the available sensor surface and the design environment of the sensor in the final
application.
