The DIY basic will be back in stock soon. What we discontinued is the DIY pro that was the larger unit but to be soldered.

The reason we did not do the AQ-Spec yet is that we are still doing a lot of research into fine tuning the accuracy of the monitor. For this we run a co-location project with more than 25 sites around the world. Here we compare the AirGradi

We used to have a DIY version that required soldering but the problem was that a number of people overestimated their soldering skills and couldn't get it done. Then obviously that is frustrating for them. So we discontinued it for now

Yes, these things have come up quite a few times. Regarding Radon there are unfortunately no 3rd party sensor modules available that we know off (and are reasonably priced). If you know any, please let us know. Regarding PoE, we have made a

With our latest firmware we now natively support Home Assistant and the monitors are auto discovered. So no need to flash ESPHome anymore. We also expose a local API that makes it very easy to make GET requests to the monitor within your lo

Achim from AirGradient here. You raise an excellent point. Often T&C are indeed just written by lawyers and potentially not being enforced at all. However, it really does restrict what you can do with the monitors in practical ways. Let

If possible mount it: - at least 1.5m above ground to avoid dust from the ground getting into the sensor - avoid proximity to HVAC system or barbecue grills etc that could influence the sensor - if possible mount it in permanent shadow so t

Yes it's easy to upgrade. You can purchase the CO2 module in our online shop under the spare parts section. The CO2 module will go into one of the PM slots. So you will have a spare PM sensor. Feel free to also contact me through our w

Yes. There are many PM maps with a lot more monitors like PurpleAir map but I don't know any for CO2 comparable to what we launched.

Yes, at some point we probably need to lift the adjustment above 400 for the automatic baseline calibration which is easily doable.
106.
by ahaucnx 2y ago
At the moment we have the automatic baseline calibration set to a default of seven days. This means the sensor modules auto calibrate to around 400ppm every week. This typically gets them very close to each other when co-located. However, a

Achim from AirGradient here. We are super thrilled about launching this and the examples that I describe in the blog post are quite encouraging that we can get some really useful data out of it. Happy to answer any questions.

Achim from AirGradient here. I fully understand your frustration. Maybe a bit of background information to put this into perspective. Until around a year ago, the open-source DIY kits where a seperate 'side project' as we focused

Achim, founder of AirGradient here. These are all valid points that came up at the beginning of the year and we took this feedback very seriously. I'm happy to let you know that we have implemented already point 1) and 2) in the latest

It would be great if this could be extended with air pollution data. Combined with weather data like wind speed and wind direction, the data could be of great use in forecasting for example air pollution from wildfires. There are some platf
