5V Household PM2.5 Detector Module Air Quality Dust Sensor TFT LCD Display Monitor
A part of the review has been auto-translated.
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.
good thank
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.
Well thought out construction, no assembly required, plug and play. Does what it says, a dht11 is used for temperature and humidity, so these are probably not the most accurate, but I bought it for the particulate matter measurement and it seems to do a good job at that. The sensor is a sharp GP2Y10. Power consumption is minimal, it will run a couple of days on a singe cell power bank with the back light switched off (a button on the side toggles the back light) The CPU is a STM8L151
