Digital Humidity Sensor SHTC3 (RH/T)
The Standard for Humidity Sensing in Consumer Electronics
The SHTC3 digital humidity sensor builds on the success of the proven SHTC1 sensor. Thanks to a broader supply voltage range (1.62 – 3.6 V) and higher accuracy (±2% RH, ±0.2°C) than its predecessor, it enables greater flexibility.
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.
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.
