AlerSense

AlerSense combines various environmental and air quality sensors with smart algorithms (because why not) and of course a smartphone app to detect the possible cause of changes that could cause an attack for asthma sufferers or those with COPD.

Personally, I think we're getting a little obsessive with our constant need for data, but for folks who have severe asthma, or who are especially worried about little ones while they sleep I think this little device could be a life saver, quite literally.
