What's up, guys? Here's a product that you absolutely have to have if you want to know what the real pollution numbers are. The pollution numbers are easily politicized in apps and on websites and can be faked without too much difficulty....but now you don't have to worry! Here is the Laser Egg...or the Laser Egg 2, I guess. It's an AQI meter that people all over China use.
The Laser Egg tells you instantly and accurately what is in the air you’re breathing, so that you know whether or not you efforts to keep your environment clean and healthy are working.
No programming. No need for a PhD in air quality. No special tools. The Laser Egg is automatically calibrated and is readable on your phone when connected to Wi-Fi. Just take it out the box and go!
The Laser Egg has a small fan that pulls ambient air in through the back of the unit and pushes it out the front. In the middle, a laser beam cuts across this air current. As particles pass through the laser beam, the beam’s light is refracted. A sensor picks up the subtle changes, and information about the size and number of particles passing through is determined through a series of algorithms.
