Smartphone sensor to tell how well you sleep

LONDON: A new sensor, once connected to a smartphone, can tell how well you sleep apart from monitoring the air quality around it.
Developed by a Finnish company called VTT, the gas sensor would make things like the detection of internal air problems easier, ayle.fi.com quoted researchers as saying.
The sleep quality can be measured with greater precision, using mobile health care applications which gauge carbon dioxide quantities, they said.
The device can monitor levels of carbon dioxide exhaled while sleeping, giving precise measurements of restful, or fitful, slumber.
“Many day-to-day issues like precision and efficiency in the workplace can depend on carbon dioxide levels and indoor air quality,” lead researcher Anna Rissanen was quoted as saying.
The tiny sensor was developed by the team’s senior scientist Rami Mannila, and is based on shining light through an air sample captured in the device.
