Humidity and temperature sensor suits wearables and mobiles

Especially suited for the consumer electronics industry, the SHTW1 humidity and temperature sensor is based on CMOSens 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, which means that SHTW1's package is no larger than the CMOSens Chip itself, despite delivering the same functionality as conventional digital humidity and temperature sensors. This eliminates any space concerns.

Intended for the wearables market, the SHTW1 could soon give glasses, watches, articles of clothing or cell phones the ability to sense temperature and humidity: it makes it possible to integrate the measurement of our environment into every facet of our lives.

As well as the low power consumption, the 1.8V operating voltage of the SHTW1 makes it suited for use in small, mobile devices. The sensor measures relative humidity across a range of 0-100% RH, with a typical accuracy of +/-3% RH. Operating over a temperature range from -30 to +100°C with a typical accuracy of ±0.3°C, the completely calibrated sensor features an I²C interface and is reflow solderable.
