Alps Electric Co. Ltd has unleashed a lineup of humidity and pressure sensors intended for smartphones and other mobile devices. The HSHCAL Series comprises capacitive digital humidity sensors in a package measuring 2 x 2 x 1mm. The HSPPAD pressure sensor range comes in a slightly larger package measuring 2.5 x 2.5 x 0.8mm.

In the humidity sensor range, Alps has redesigned the digital ASIC element to reduce the package size. As with the established analog HSHCA Series product, the HSHCAL Series employs proprietary sensing film for the sensor part. In addition, an original sensor configuration enables temperature compensation within the sensor device.

The HSPPAD pressure sensor range is a digital-output series based on the analog HSPPA Series and also has a built-in temperature compensation function. The sensor has a wide measurement range of 300-1,100hPa, stated the company.

Mass production of both families began in April 2014.
