Humidity Sensor for Battery-Driven Applications

Published on : Tuesday 30-11--0001

The SHTC3 is a digital humidity and temperature sensor optimised for battery-driven applications and high-volume consumer electronics. The sensor has been designed to overcome conventional limits in size and power consumption in order to fulfil current and future requirements, and offers an unmatched performance-price ratio. The SHTC3 improves the performance and flexibility of the SHTC1, while maintaining its proven reliability.

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. Thesmall 2 x 2 x 0.75 mm3 DFN package enables applications in even the most limited space. The sensor covers a humidity measurement range of 0 to100%RH and a temperature measurement range of-40°C to 125°C with a typical accuracy of ±2%RH and±0.2°C. The broad supply voltage of 1.62 V to 3.6 V and an energy budget below 1 μJ per measurement make theSHTC3 perfectly suited to mobile or wireless applications powered by battery.

With the industry-proven quality and reliability of Sensirion’s humidity and temperature sensors providing constant accuracy over a large measurement range, the SHTC3 offers the best performance-price ratio. Tape and reel packaging combined with suitability for standard SMD assembly processes make the SHTC3 ideal for high-volume applications.
