Sensirion Presents Humidity, Temperature Sensor
February 23, 2014. At the Mobile World Congress 2014, Sensirion AG is presenting its SHTW1 humidity and temperature sensor—for the wearable and mobile market—with chip-scale packaging technology.
With miniature dimensions of just 1.3 x 0.7 x 0.5 mm, SHTW1 could 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 1.8 V and the low power consumption of just 2 µW at 1 measurement per second provide a basis for using the sensor in small, mobile devices. The device measures relative humidity across a range of 0% to 100% RH, with a typical accuracy of ±3% RH. The temperature measurement ranges from -30 °C to 100 °C with a typical accuracy of ±0.3 °C. The calibrated sensor features an I2C interface and is reflow-solderable.
