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.

 

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.
