Sensirion announced a new ultra-low power humidity sensor SHTC3 for mobile and battery-driven applications. The SHTC3 is a digital humidity and temperature sensor optimized 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 fulfill 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 bandgap temperature sensor, analog and digital signal processing, A/D converter, calibration data memory, and a digital communication interface supporting I2C fast mode. The small 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 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. The broad supply voltage of 1.62 V to 3.6 V and an energy budget below 1 μJ per measurement make the SHTC3 perfectly suited to mobile or wireless applications powered by battery.

Tape and reel packaging combined with suitability for standard SMD assembly processes make the SHTC3 ideal for high-volume applications.
