I found this old thread about air quality sensors on TTN. Could @Wojtek tell us if something has happened since then ?
I think Wojtek is the author of the blog post by iotman that you refered to in your earlier post.

In that case I went full circle without knowing it. Thank you for noticing!
Hello
The hardware is still being tested While we still adding finał touches to the firmware. At this point we are still tweaking calibration mode and energy saving modes. Provisioning done over LoRaWAN, pretty cool actually.
Thanks
Wojtek
Thank you for giving a status report. Provisioning over LoRaWan sounds great! Are there any specs you can share with us already ? Primarily regarding the sensors. And what is your planned schedule for getting the product ready ?

Because of the domain name, a little bit misleading URL, but interesting content about measuring pollution in different particle sizes. Though not calibrated, they seem to come very close to calibrated devices. Would certainly provide usefull indicative figures for citizens who suffer from traffic and wood stove pollution.
Hi,
We are measuring the following data:
CO
NO2
O3
PM2.5
Temperature
Humidity
GPS coordininates
Optionally, PM10 and SO2
Sensors, with exception of SO2 need to be calibrated and we provide such mechanism. It will require “clean room” or something close to it and can be invoked using our LoRaWan provisioning mechanism. Also, calibration values can be pushed to node over LoRaWan. In addition, we support number of different operating modes, especially for GPS, where you can do a lookup once or do it in a continuous mode or cold standby mode (shut down gps power between measurements). In addition, user can obviously specify time measurements. Each node uses Lithium Polymer battery which can be charged using a solar panel or just plain USB PS. We are extremely busy, but you should see more details on our web site soon. We haven’t decided yet if we will provide persistent data storage, but today we use InfluxDB and Grafana to visualize the results
Thanks
Wojtek

Hi Wojtek are these LoRa devices available yet? I Am really interessed in some testing results
We are just waiting for a final pre-production batch. We expect to have first units available in mid September. We end-up removing SO2 sensor and adding barometric pressure sensor due to requirements driven by our first volume customer.
We will also provide application server which will interpret the data and store it in InfluxDB for persistency. In addition, there is a RESTful API for provisioning (CLI and web based) parameters of the node. Nodes will operate on TTN and/or private network based on brocaar Lora Server. Stay tuned…
Wojtek
Do you have a url of your company?
Hey Wojtek,
is your air quality sensor already available ?
Regards Martin
Yes, we are on the second production batch with small quantities. We also just about tun first production batch of Green House units with CO2 and light sensors. Please contact me directly over email for details
Hello
Look: http://luftdaten.info/feinstaubsensor-bauen/
German :-), but they talk english too.
Greet`s
edit: Ups. Not connected to TTN yet. :-/
Hi Wojciech,
I visited your company website and it says second batch is coming soon. I’ve subscribed for updates but wondering if you have any you can provide here? I would contact you via email but I don’t know where to find it.
I am keen to bring in air quality sensors to my company and start using them commercially.
Hi we build an air quality concept for buildings named smartconcierge and measure movement,light,co2,temp and humidity in one sensor incl. dashboard to display. now working on predicitive maintenance. If you need more info just let me know.
maybe you can tell us more here on the forum, is it a commercial product. for example, pictures ect.
carefull… your product name SmartConcierge is in use
