A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Out of sight might mean out of mind, but it doesn’t necessarily mean out of danger, particularly in the case of small airborne particles. Such particles can severely affect your health, with effects ...

It’s an unfortunate reality that for many of us, our air isn’t nearly as clean as we’d like. From smog to wildfires, there’s a whole lot of stuff in the air that we’d just as soon like to keep out of ...

The hardware coming out of [Dr. Peter Jansen]’s lab is the craziest stuff you can imagine. He’s built a CT scanner out of plywood, and an MRI machine out of many, many turns of enamel wire. Perhaps ...

Panasonic is aiming at indoor air quality monitoring with a particulate matter sensor based on laser scattering. “SN-GCJA5 features an innovative optical sensor assembly to provide reliable operation ...

Description: Designed to measure IAQ, this product is a contamination-resistant optical sensor that enables accurate measurements throughout its projected lifetime of more than eight years. It ...

Monitor smoke and airborne particulates with the new PMX sensor by EMX Industries. The PMX Particulate Monitor can be used in many applications to detect change in light transmission caused by smoke, ...

Air pollution involving very fine dust, such as PM2.5 particles, poses a serious threat to human health. Scientists in Austria have developed what they call the smallest particle sensor in the world, ...

It is slightly smaller than two one-cent coins stacked on top of each other, is particularly energy-efficient due to its size, requires no maintenance and can be integrated in mobile devices. It is ...

A new add-on, or 'hat', is available to attach to the Raspberry Pi computer to create a device that measures air quality, temperature, air pressure, humidity, light, and noise. The hat, dubbed Enviro+ ...
