The Department of Homeland Security (DHS) has started working with mobile phone manufactures, including Qualcomm, Apple, Samsung, and LG, to begin implementing poison chemical detectors. The detectors will be used to help notify users of a chemical release. The implementation of this chip would also be linked to a network,which through multiple unique detections and geo-location, would help to isolate the area where chemical exposure occurs.

With this network of toxic chemical detectors, first responders could quickly address the situation based on the data being sent by the smartphones. Besides chemical fumes, I wonder what type of applications could be built to use this sensor? An app to sense what type of food it is by scent perhaps?
