Swiss sensor manufacturer Sensirion announced the successful integration of the world's smallest humidity and temperature sensor into smartphones at the MWC 2013, setting a new standard for ambient sensing.
Sensirion's previous sensor models already provided a complete sensor solution for mobile devices and have been successfully integrated into millions of mobile phones. With the new SHTC1 humidity and temperature sensor, Sensirion has responded to calls from industry 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 sensor 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 temperature sensor delivers miniature size with maximum performance.
