Environmental Sensing For A Smarter Life

January 28, 2014

STAEFA, Switzerland - At the Mobile World Congress 2014, Sensirion AG is presenting its latest humidity and temperature sensor SHTW1, which opens up new possibilities in the wearable and mobile market with its chip-scale packaging technology. This global innovation combines minimal size with maximum performance to define the latest generation of humidity and temperature sensors, enabling unprecedented opportunities. Sensirion creates space for new ideas - there is no limit to the range of possible uses of the tiny SHTW1.

With its size and low energy consumption, the new SHTW1 humidity and temperature sensor meets the exacting expectations of the consumer electronics industry. Like all Sensirion sensors, SHTW1 is based on CMOSens(R) Technology, which integrates the sensor component and the evaluation circuit on a single semiconductor chip. Sensirion is the first company to use wafer-level chip-scale packaging technology in humidity and temperature sensors. This means SHTW1's package is no larger than the CMOSens(R) Chip itself, yet the SHTW1 has the same functionality as conventional digital humidity and temperature sensors. So when it comes to usability, space is no longer a concern.

With miniature dimensions of just 1.3 x 0.7 x 0.5 mm, SHTW1 will revolutionize the market and create the foundation for an endless array of applications. SHTW1 could soon give glasses, watches, articles of clothing or cell phones the ability to sense temperature and humidity, making it possible to integrate the measurement of our environment into every facet of our lives.

The operating voltage of 1.8V and the low power consumption of just 2 microwatt at 1 measurement per second provide an optimal basis for using the sensor in small, mobile devices. As the specifications demonstrate, performance was not sacrificed to achieve the tiny size: it measures relative humidity across a range of 0% to 100% RH, with a typical accuracy of +/-3% RH. The temperature measurement ranges from -30 degrees C to 100 degrees C with a typical accuracy of +/- 0.3 degrees C. The completely calibrated sensor features an I2C interface and is reflow solderable.

With millions of sensors already in use, Sensirion's years of experience and the competent application know-how it offers its customers are invaluable in the successful integration of the sensor in complex solutions. It has once again developed the smallest sensor with the biggest performance on the market with the SHTW1 humidity and temperature sensor. Combined with first-rate implementation support, Sensirion is undoubtedly a step ahead of the competition.
