    Works great as advertised, reports same pm2.5 count as my air purifier, I'm happy it comes with a usb-uart adapter making it really easy to get started, libraries for python easily found online to communicate with sensor and keep track of your own air quality.

    A bit slow shipping... But the product quality is great.. Tested with the available GitHub code and quiet accurate readings... Works with ESP32 and Arduino both... Go for it !!

    This sensor also from costly, but, can use for education or simple home devices. For professional air-cleaners or medycal instrument i can recomended buy another, with more fast time of stabilisation, and more faster reaction. Some more important things: When you connect and run, you need wait arround 1 minuts for get aproximate real values. this time need for stabilisation sensor. If you try use sensor in room, and after yu are goind to street - please wait arround 5 minuts for stab, because the optical sensor, and after replace thermal mode, sensor need again thermo-stabilisatioin before measuring. Software for testing this and ssome other sensor we gift to banggood, and you can download from this link:[v1.0].zip

    A good precise measuring equipment. It is built in and it is difficult to dismantle everything again. You can see the result measured by the SDS011 on the display that it works fine. Good stuff. Greeting from Joost from the Netherlands

    The sensor looks ok. I expected the cover to be made from metal but is seams it's chromed plastic. That doesn't bother me to much as long as it works well. I've received it 5 days shy of a month from when I've made the order.
