How much would it cost me to install a modulair-PM on my rooftop, assuming I did the work? I’m just an individual, i just want transparent information. I don’t want to “contact sales” as it says on the link from that blog post.

Thanks for the interest! We have transparent pricing here: https://quant-aq.com/pricing

Short answer, $1500 + $300 annually (includes cellular, realtime data calibration in our cloud, and full API access).

Relevant to the topic above, we are building for a slightly different market than AirGradient, and want to make sure we're an appropriate solution for potential customers -- you might genuinely be better served by a different product! As such, we're currently not optimized for low touch single sales to individuals, but it's something we'd like to improve in the future.

If you do contact sales, and we end up being a good fit for what you're looking for, we'd love to help!

I’d be interested in a prosumer version of this that ditches the LTE and cloud system for wall power + WiFi or (ideally) PoE with a fully local backend via home assistant

I am curious, how do you do real-time calibration in the cloud?

You could buy a Bosch BME680 or similar for $20 and add it to a Pi or Arduino.

A commercial model is around $200.

There are a lot of options so decide if you want to build it or buy it and plug it in!

Then you can list your data on a site like https://explore.openaq.org/

The BME 680 does temperature, humidity, barometric pressure, and VOC gas sensing. Maybe there's something reasonably-priced that does particulates, but this doesn't seem to be it. What's a good alternative?

That looks awesome, thanks! I already have some ESP32 devices acting as weather sensors that log to a Raspberry Pi over MQTT. I might have to add this too.

Very impressive. I looked up that Bosch device: https://www.bosch-sensortec.com/products/environmental-senso...

Then, I found a board from Adafruit. The chip is so tiny in the Adafruit photo!
