Digital Humidity Sensor SHTC1

The SHTC1 is a digital humidity sensor designed especially for high-volume consumer electronics applications. This humidity sensor is strictly designed to overcome conventional limits for size, power consumption, and price-performance ratio, in order to fulfill the current and future requirements of the consumer electronics market.

Sensirion’s CMOSens® technology offers a complete sensor system on a single chip, consisting of a capacitive humidity sensor, a band-gap 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 mm³DFN package enables applications to be placed 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°C to 100°C with a typical accuracy of ±3 %RH and ±0.3°C.

The operating 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 lowest power budgets. With the industry-proven quality and reliability of Sensirion’s humidity sensorsand constant accuracy over a large measurement range, the SHTC1 humidity sensor offers an unprecedented price-performance ratio. Tape and reel packaging together with suitability for standard SMD assembly processes make the SHTC1 predestined for high-volume applications.
