Product Summary
The SHTC1 is a digital humidity and temperature sensor
designed especially for high-volume consumer electronics
applications. This sensor is strictly designed to overcome
conventional limits for size, power consumption, and
performance to price ratio in order to fulfill current and
future requirements. Sensirion’s CMOSens® technology
offers a complete sensor system on a single chip,
consisting of a capacitive humidity sensor, a bandgap
temperature sensor, analog and digital signal processing,
A/D converter, calibration data memory, and a digital
communication interface supporting I2C fast mode. The
ultra-small, 2 × 2 × 0.75 mm3 DFN package enables
applications in even the most limited of spaces.

Benefits of Sensirion’s CMOSens® Technology

The sensor covers a humidity measurement range of 0 to
100 %RH and a temperature measurement range of –30
to 100 °C with a typical accuracy of ±3 %RH and ±0.3°C.
The operation voltage of 1.8 V and an energy budget
below 1 µJ per measurement make the SHTC1 suitable
for mobile or wireless applications running on the tightest
power budgets. With the industry-proven quality and
reliability of Sensirion’s humidity and temperature sensors
and constant accuracy over a large measurement range,
the SHTC1 offers an unprecedented performance-to-price
ratio. Tape and reel packaging together with suitability for
standard SMD assembly processes make the SHTC1
predestined for high-volume applications.

High reliability and long-term stability
