[Chris] has allergies, asthma, and uses a wood burning stove. You can imagine why testing his air quality might be something he’d be interested in. He has a very nice $290 laser particle coun… ...

The gas analysing detector is backed by an AI algorithm. Its outputs can include ‘index for air quality’ (IAQ), biogenic volatile organic compounds (bVOCs) or CO 2-equivalence in ppm. “The air quality ...

A research team develops a real-time humidity sensing optical sensor. The response time of the new sensor is 10,000 times faster than the conventional sensors and can be mass-produced at low cost.
