Scientists developed a miniature gas sensor for mobile devices – Applications from monitoring air quality to healthcare & wellness

VTT Technical Research Centre of Finland has developed a miniature gas sensor that can be connected to mobile devices. Gas measurements made with smartphones will make activities such as the detection of internal air problems easier. In addition, sleep quality will be measurable with greater precision, using mobile healthcare applications which gauge carbon dioxide quantities. Many sensor developers are interested in using smartphones to measure gas concentrations. "This is probably due to the spread of the Internet of Things (IoT), which enables indirect observations of a range of
