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

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

applications in even the most limited of spaces.

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.
