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.

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…

Awesome work! Do you have any plans to add/track gas pollutants? I run a similar open source app specifically for my little community in Gary, IN https://millerbeach.community and run a RAMP monitor provided by a local company Sensit Technologies, and a PurpleAir II and have about ~4 years worth of data in 15 min intervals. I've been meaning to swap out the PurpleAir with another, but I'll swap it out with this inste…

We started testing electrochemical NO and NO2 sensors from Alpha Sense in our lab and are in the early stages to design a unit that would also measure these gases but we are many months away to have something in the market.

I think the website is very unclear about what you get, other than part names. What can the pro do that the normal can't do? Can I connect the TVOC to the non-pro?

The TVOC module is only for the PRO indoor kits. The BASIC kit does not have space for the TVOC module.

The PRO comes with a nice plastic enclosure, has a larger display and due to its larger size measures temperature and humidity more accurately (since there is more space, the temperature sensor has more distance to active components that heat up).

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.

I appreciate when things come up again. Obviously enough people either haven't heard of it or want to talk about it again for it to be upgoated to the front page.

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'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 provide at a premium that these cheaper monitors can't.

I'd be a buyer if you had an indoor unit with a radon sensor.

We have looked into adding a radon sensor but it is very difficult to get an off-the-shelf radon module in the market that is reasonably priced. If any of you can recommend a module I would be very interested to hear.

Repackaging these sensors might be a better play than an OTS procurement model. Lots of people are making pretty packages for commodity sensors. Few are developing new sensor packages.
