Thanks, this is great feedback and we definitely lack these links in that new copy. I will add them soon. In the meantime: Build instructions: https://www.airgradient.com/open-airgradient/instructions/di... BoM, s

The tooling for the plastic enclosure was quite complex and time consuming. If there is interest I can write a blog post about it.

Most of the times the sensor modules are actually pretty accurate but the heating up of the enclosure e.g. from heat radiated by the MCU creates the issues. In our indoor monitor it took us several months to get the airflow through the encl

This page about the monitor is brand new and contains quite a lot of information that has never been published/posted before, e.g. the exact specs of the monitor and explanations about the enclosure design.

There are two main advantages of having two sensors: a) Data quality: You can detect if one sensor fails as the two readings will start to deviate and then replace the faulty one b) Extend the life of the monitor: The PM sensors with the la

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.

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]. [1] https://www.airgradient.

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 mon

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).

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 accu

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.

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.

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.

Yes, we also have a popular open-hardware, open-source indoor air quality monitor that measures CO2, PM, Temperature and Humidity. You can also get an optional TVOC module that can measure chemicals and NOx. This version we currently only s

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 p

Achim from AirGradient. We design and manufacture open-hardware low-cost air quality monitors. We sell and maintain very popular DIY air quality monitoring kits [1]. I think there are a few things that set us apart from other hardware start

We are working on an integration with openAQ [1] to share air quality with them (opt-in for people that use our data platform). OpenAQ is an NGO with the mission to collect air quality data from all kinds of sources from around the world an

I think there are quite large benefits in sharing outdoor pollution data compared to temperature and humidity due to its much larger health impact.

This is funny and sad at the same time.

This topic is something that irked me for quite some time and I am looking forward to the discussion here.

We are not aware of any suitable radon module on the market that we could easily integrate. I think airthings use their own developed module.

Currently we ship all kits from Thailand but setting up some fulfillment in the US and EU could be something we might do in future. Currently most customers do not get charged customs and VAT.
