Banggood

This is a good PM 2.5 dust monitor. The instrument seems to be accurate as I cross checked with a branded instrument. It has bright LCD screen. The sensor is the well known dust sensor from Sharp. Appears to be a Sharp Optical Sensor GP2Y1010AUOF. Takes about a minute to display stable readings.

Very good build quality and air quality detector is working good this is my very first product from banggood i am totally satisfied with this product.

Thanks to this device, now I can keep on track in room PM 2.5.

compact size, USB powered , temperature,humidity and PM 2.5 measurement,

Now I know how much pollution in my appartment :)

Arrivato prima del previsto

Seems to works well in the right conditions and placement

Very simple to use.

pretty good reading. i matched it with my air purifier and it was 5 points plus minus. sturdy build. you need to keep it at 1 place for it to be effective.

The device worked well during our bush fires. can recommend.
