    This is a very interesting device; I bought it to monitor dust levels in my home workshop and to measure if dust filters were being effective. With it i was able to significantly reduce dust to the point that my Indoor air quality now closely follows with local Outdoor air quality monitoring stations !! I added a wireless connection so it could be moved around and still log data to my shop PC. The only problem I encountered was that the supplied connector would not stay connected no matter how hard i tried to press it in. Eventually i hot glued the connector in place. Even with the connector problem i would still highly recommend this item.

    A very solidly built and well constructed PM 2.5 sensor. I have found it to be very accurate when comparing it to other PM 2.5 monitoring devices. The price is literally about half of what they charge everywhere else for it. Shipping was very fast I got it within a week. I'm really looking forward to wiring this up to an Arduino and sitting at the permanent monitoring station. I will buy many more of these at this price.

    Arrived in Serbia after 18 days. Wish it were packed better since it is sensitive electronics.

    The only negative note on the connector. Not really of excellent quality and the choice to use only black and red colors by matching the red with the negative power supply is not a genius

    Arrived in 2wks. Works with esp8266. Accurately reads smoke (50+ ug/m3) from wildfires 600+ miles away in Washington and Oregon (reflecting local weather forecasters air quality index).

    I received my PMS5003 this morning. I have it up and running thanks to Tasmota with a Wemos D1 Mini. This proves that my Filtrete 2200 air filter is removing smoke during this terrible fire season.

    Really fast shipping. It took 8 days to arrive. Everything seems ok. Tested it with an arduino and it worked. Now i will implement it with ESP and Home Assistant.
