    Great addition to ecosystem
  

*by P***G on Reviewed in the United Kingdom on 2 February 2024*

If you’re interested in air quality or - as I did - want to contribute to community weather data, this is a great addition to the Ecowitt ecosystem.

    Be careful what you wish for...
  

*by R***E on Reviewed in the United Kingdom on 7 January 2022*

Just brought an Ecowitt compatible weather station from Germany and saw this sensor at a good price.  Figured it would give more interesting data than the lightening one that I was interested in.Popped in some batteries and the HP2550 console found it almost instantly.  It sat inside for a couple of hours reading zero particles (good air quality) so I lit a candle in the same room.  Sensor works!  And candles are really, really, really bad for your air quality it seems.  Air quality improved slowly over the next few hours and only really peaked cooking Christmas dinner.Thought it might be malfunctioning, but it seems candles, roast dinners and fried breakfasts cause the most air pollution inside according to a well know search engine.  It's now outside and telling me that my seaside air is good except for New Year's Eve when the Air Quality changed to moderate after the firework display about 1 mile away.My only grip is that you can't set an alarm on the console to alert you like you can for other sensors.  Hopefully a firmware upgrade will fix this.  It does however upload the data to the Ecowitt website so you can track it over a period of time which really is how it should be used.

    Works out of the box
  

*by D***. on Reviewed in the United Kingdom on 19 February 2022*

Works right out of the box on USB power for me.The CO2 monitor levels off in fresh air at just under 400, so reads a little lower than it should, but given that the variation in the house is up to 1000 (and sometimes higher) this isn't a problem.The PM2.5 sensor is a lot more stable than Ecowitt's older models, showing they have put some effort into improving the design. The PM10 seems to work well too. Both detect the slightest increase, for example from use of the frying pan several rooms away.Others have said it's "noisy". I hate noise, am a very sensitive sleeper for example, and I have this device running right in front of me in my home office. I can barely hear it at night, and during the day it's negligible. I can only suggest they had a dodgy fan in theirs (it happens). Noise is not a problem for me at all.Watch out for vouchers and offers, they come and go on this device.
