New Ultra-Small Digital Humidity Sensor: Simplicity Meets Proven Performance

Sensirion, the world’s leading manufacturer of humidity, temperature and flow sensor solutions, presents its second generation WLCSP (wafer-level chip-scale package) humidity sensor: the SHTW2. The SHTW2 humidity sensor comes in a flip chip package – an established technology that represents one of the simplest and smallest possible ways of packaging a semiconductor chip and results in a tiny footprint of 1.3 x 0.7 x 0.5 mm³. The SHTW2 also pioneers a new category of ultra-small humidity sensors suitable for applications with the tightest space constraints.

The SHTW2 is based on Sensirion’s CMOSens^® Technology, which offers a complete sensor system on a single chip with a digital I²C interface. The sensor is fully calibrated and 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 SHTW2 perfect for integration in consumer electronics that run on the tightest power budgets, such as mobile phones, wearables and Internet of Things (IoT) applications. With the industry-proven quality and reliability of Sensirion’s humidity and temperature sensors, and constant accuracy over a large measurement range, the SHTW2 offers an unprecedented price-performance ratio. Tape and reel packaging and suitability for standard SMD assembly processes ensure the SHTW2 is ideal for high-volume applications.

In combination with Sensirion’s complete solution approach, the new SHTW2 humidity sensor is your number one choice for highly reliable humidity and temperature measurement in consumer electronics and IoT applications. The complete solutions approach means that Sensirion not only provides sensor hardware, but also supports customers with hardware and software integration as well as by developing algorithms and use cases.
