Compact Humidity Sensor Consumes Little Power

Sensirion’s SHTC3 is promoted as an ultra-low power humidity sensor groomed for mobile and battery-driven applications. The digital humidity and temperature sensor is optimized for battery-driven applications and high-volume consumer electronics. It improves on the performance and flexibility of the SHTC1, while maintaining equivalent reliability.


The company’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 2 mm x 2 mm x 0.75 mm3 DFN package enables applications in limited space.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.


The sensor covers a humidity measurement range of 0 to 100% RH and a temperature measurement range of -40°C to +125°C with a typical accuracy of ±2% RH and ±0.2°C. For greater details, peruse the SHTC1 datasheet.
