If the device worked with ZigBee, I would get it immediately. However, it seems to support only WiFi, which means if someone gains physical access to the AirQuality monitor (which isn't exactly difficult since it is placed outside), they can potentially extract the WiFi password and gain full access to my network.

Yes that's a good point. It probably makes sense to put it on a separate WiFi network (or a guest network) if access to the monitor is possible for unauthorized persons.

Definitely recommend a separate 2.4ghz N-mode only wifi with separate passphrase and client isolation on a different vlan with routing only out to the internet for all IoT stuff.

I strongly recommend to not always trust everything because it's open source. Air Quality as all different weather ingredients are measure and there is a big difference how you measure. I am not advocate of any "pro" solution. I just want you to know to check many sources.

How well does the USB-C cable (and the rest of the PCB!) hold up outdoors? Especially in areas with salt, like near a coast or a place where salt is used on the roads in winter? From what I understood the sensor isn't sealed?

At the moment it is not sealed. We are currently looking into conformal coating options and will probably have this available in one of the next batches (we are currenly checking what coating our PCB assembler can do).

I'm the founder of AirGradient and last year we have decided to focus our company on open hardware air quality monitors that we produce professionally. Our outdoor monitor Open Air has been designed from the start as an open hardware project with a beautiful plastic injected enclosure to demonstrate that open source hardware can look and perform on the same level like traditional products. We do also work intensively…

I'm struggling to see the benefit of your product. Apart from the outdoor element. You can buy a 4 in 1 air monitor from Amazon for half the price (Co2, PM, Temp and Humidity) i.e. https://www.amazon.co.uk/Indoor-Air-Quality-Monitor-Multifun... There are others with 6 in 1 with app control for less. Aren't there other sensors that would be more useful providing better insights on pollutants and health you could provi…

We use high quality sensor modules like e.g. the SenseAir S8 NDIR CO2 sensor that is made in Sweden and also Sensirion modules from Switzerland. These are much more expensive than less accurate sensor modules that you find in many other monitors.

Yes, I totally agree. This is why we do extensive research to ensure the accurateness and reliability of the monitor against reference instruments. You can read more about it on our research page [1].

Time for the usual reminder that there is a search function on the bottom of every single YC page. Air gradient has been extensively discussed here multiple times already.

The guy who runs air gradient posts his articles here pretty frequently. Not sure at what point, if any, it breaks the rules. It definitely feels a little spammy to me though.

I think there is no rule limiting new links. If it gets voted up, it makes it. And reposting existing links is ok every 6 months or so (I think).

Can I get the data as CSV or similar for custom presentation, backup and analysis?

If you use our data platform, you can easily export an csv file with all the data in our database. But since it is open source you can also easily adjust the firmware and send the data to another server.
