AirVisual Outdoor – Outdoor Air Quality Monitor, Detects PM1, PM2.5, PM10, Optional CO2, Temperature, Humidity, Pressure, Modular Sensor Design, Wi-Fi, LAN, German Made

I bought the outdoor monitor to add to my suite of outdoor data with my Tempest weather station. I am very happy with the station and the accuracy of the reporting. Here's the breakdown. Pros - Extremely easy installation. PoE (injector included) - if you hardwire it into a switch that's it. It's online ready to go. - 2 extremely high quality CAT6 cables are included - Aforementioned accuracy - Charting on the web app is great, months, days, hours, and minutes - Has an API that can be used to make custom displays etc (see con below) - Adding modules is as easy as inserting it into the device Cons - The CO2 module is *not* given away. You will pay a hefty sum for that data - Adding the CO2 module still leaves an empty slot in the device. I would love to add an O3 module to that slot. Con is that there is a slot that isn't utilized. - In order to gain access to the API of the device you *have* to share your data with the community. Personally, I am not a fan of this. I don't need people to be able to lookup on a map the exact location of a $400+ device (with CO2 module). Solution to this is make the location in an adjacent neighbor's yard! ;) - The app is pretty meh. The best data you can get is out of the website. At least on iOS it does have a widget which is ok. - The API does not include particle counts and there is no formula to extrapolate that data. Extremely minor quibble, but it's on the website as a data pid, but not in the API. Summary This device works extremely well hardwired into a switch. My monthly uptime report shows 100% uptime with destroys all the Purple devices along with anything else in the area. If I look at my chart on the community it's complete, anything else has hours of gaps. That right there tells me it's a good setup. The AQI readings are spot on with what others report, you can see spikes from environmental impacts in real time. I would recommend this to anyone interested in monitoring AQI, one of the things that really bothered me with Purple is that I was required to pay $40 for an AC adapter since it is NOT included. So really that makes this device quite the bargain against a Zen. The only reason I rated it 4 stars, not 5 is that I really dislike conditions tied around API access and I really want more data considering I have a completely empty slot in the device. I would love to see the price pushed down just a bit and more module options. Again, extremely happy with the purchase. Edit: I have increased the review to 5 stars based on product support. I had an issue where one of the PM modules had the fan seize which caused it to make noise. I called support and they asked that I identify the module, ensure it was free of dirt and debris. If it didn’t fix the issue, call back. It didn’t fix the issue so I called back. The support team validated my serial number/warranty and shipped out a replacement no cost no return of the faulty module. Furthermore, this was not an offshore call center. The experience was so refreshing they earned that last star.

Simple. Works. The software is a bit confusing and clunky and synchronization between device/mobile/cloud wonky but once that is overcome and learned it doesn't matter. The important things are there so I don't dock a star. This has been an important add for HVAC control due to local use of heavily polluting wood burning. By it I can halt an ERV automatically via IFTTT smart plug or manually and switch to a MIRV 16 filter if necessary, but generally just stopping the ERV overnight is enough along with a MIRV 13 on the furnace to keep indoor AQI well in the green. But if that stops working in the winter a modification to a HEPA pre-filter on the ERV or upgrading to a HEPA capable ERV will be sufficient. Great product and it does exactly what I needed. Well done! Please keep it simple and indoor + outdoor + IFTTT integration options. Other competitors with hubs and a multitude of sensors are over complicated in my estimation. This is perfect.

I regret purchasing an IQAir sensor. The product itself is unreliable, but the real failure is their nonexistent customer support. When you call in, the representatives have zero training, no technical knowledge, and no ability to actually troubleshoot the product. They’re simply there to answer the phone and tell you they’ll “escalate” your issue. The so-called tech team? Completely unresponsive—emails go unanswered, and despite multiple follow-ups, I’m still waiting for a callback from a supervisor. The initial issue was simple—my sensors were reporting erratic data. I attempted to replace them myself, but the data remained inconsistent. While other sensors like PurpleAir and AirGradient reported low particulate levels, the IQAir sensor’s algorithm inflated AQI readings significantly. For example, my sensor’s raw data might show a PM2.5 in the single digits, but the public AQI output would report 55. This suggests their system manipulates readings to influence publicly available air quality data rather than reflecting actual conditions. On top of that, their dashboards are completely closed off. Historical data is poorly visualized and lacks transparency. If you’re looking for a reliable, open-data air quality sensor, I strongly recommend AirGradient, which allows for full data publication and transparency. PurpleAir is also a solid alternative—while I’ve seen some sensor drift over time, their platform is much more open and useful than IQAir’s locked-in, opaque system. Bottom line: IQAir sensors are overpriced, inaccurate, and completely unsupported. Do yourself a favor and go with a company that actually values its customers. I contacted the CEO of North America. Will update if I get a response.

Requires a factory reset to use ethernet if wifi was previously configured and the product uses non-standard passive POE. The modular sensor form factor has massive potential if IQAir chooses to expand beyond just the optional CO2 sensor.

The product quality is really good, no doubt about that. Installation process also very simple. Unfortunately the wall plug inside the box was upside down, and I've to contact seller for a replacement. They answered in a couple days and the problem solved less than 2 weeks. The local team (Mr. Kyle) send me the alternative wall plug which solve my outdoor setup problem.

Jestem bardzo zadowolony z zakupu tego miernika jakości powietrza na zewnątrz.

Easy to set up and easy to use. It is amazing how fire smoke affects the air.

Die Montage war dank des PoL leicht. Ich bin gespannt ob es wie angekündigt weitere Sensoren geben wird, 2 Schächte hätte ich nun noch frei.

good quality and function
