The SHTW2 is based on Sensirion’s CMOSens® Technology, which 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.
The humidity sensor covers a humidity measurement range of 0 to 100 %RH and a temperature measurement range of –30°C to 100°C with a typical accuracy of ±3 % RH and ±0.3 °C. The operating voltage of 1.8 V and the low power consumption make the SHTW2 humidity sensor suitable for wearable applications running on the tightest power budgets. With the industry-proven quality and reliability of Sensirion’s humidity and temperature sensors and constant accuracy over a large measurement range, the SHTW2 humidity sensor offers an unprecedented price-performance ratio. Tape and reel packaging together with its suitability for standard SMD assembly processes make the SHTW2 predestined for high-volume applications.
