WLCSP Digital Humidity and Temperature Sensor - SHTW1

Product Specification

SHTW1 Digital Humidity and Temperature Sensor Product Summary
The SHTW1 is a digital humidity and temperature sensor in a wafer-level chip-scale package (WLCSP). This type of package opens up a new category of ultra-small humidity sensors which are suitable for applications with the tightest space constraints. The SHTW1 is designed especially  for  high-volume  consumer  electronics applications. The sensor is based on Sensirion’s CMOSens ® technology, which 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 sensor covers a humidity measurement range of 0 to 100 %RH and a temperature measurement range of -30 to 100 °C with a typical accuracy of ±3 %RH and ±0.4°C. The operation voltage of 1.8 V and the low power consumption make the SHTW1 suitable for mobile or wireless 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 SHTW1 offers an unprecedented performance-to-price ratio. Tape and reel packaging together with suitability for standard SMD assembly processes make the SHTW1 predestined for high-volume applications.
