MWC: Measure weather with your phone

At this year’s Mobile World Congress kicking off in Barcelona on Monday, Swiss sensor manufacturer Sensirion will announce the integration of the world’s smallest humidity and temperature sensor into smartphones.

Sensirion’s previous sensor models already provided a complete sensor solution for mobile devices and have been successfully inte- grated into millions of mobile phones. With the new SHTC1 humidity and temperature sensor, Sensirion has responded to calls from in- dustry and developed the world’s smallest sensor in its class. It measures just 2 mm x 2 mm x 0.8 mm and is based on proven CMOSens Technology, which combines the sensor and processing electronics on a single silicon chip to achieve the tiny device size.

The sensor measures relative humidity over a range of 0 to 100% RH with a typical accuracy of ±3% RH. The temperature measuring range is -30 to +100 °C with a typical accuracy of ±0.3 °C. The sen- sor is fully calibrated, has a digital I2C interface, and is suitable for

reflow soldering. This makes it compatible with standard industrial mass production processes for electronic modules. To ensure effective integration of the sensor in complex applications and a smooth implementation of projects, Sensirion draws on its many years of experience with the deployment of millions of sensor products. The new SHTC1 humidity and tempera- ture sensor delivers miniature size with maximum performance.
