I'm designing a new air quality monitor!

That's an interesting idea. We could technically add that serial port to the device to broadcast raw data. What data platform are you currently using?

The raw data from our station is currently sent through wifi and is calibrated/corrected over the internet. Would access to wifi difficult to handle?

That's exactly right. We need measurements of T/H for correction and the closer to the gas sensor, the better. We actually do not perform correction internally but over our internet server and provide calibration coefficients back. The reason for that is that we would like to be able to improve our correction algorithm over time and use the history of the sensor in the calibration. Is internal calibration is important to you?

good morning

this looks promising I have been on the edge for sometime to purchase a AIR QUALITY SENSOR i did order one for our home indoor use which is stuck in customs .However do you have an API or raw data access as I would introduce the option for the template I design . example of using purple air currently alongside weather station data .

do you foresee any problems shipping to Turkey if I decide on one and are there any realtime internet display of these in use .as I said been on the edge for a while but sooner or later I will buy one .

air quality simple display in bottom right hand corner and yes its color coded according to the familiar air quality colour schemes

I would definitely be interested in this if I was given the capability to display the data on my own website. With Ken's Saratoga Templates or a standalone website.

You need to allow a standalone (i.e. not connected to your server) version - too much cloud stuff does not work with remote areas and they seem to have a way of being locked to a vendor.

Hi Brian,

For the moment I did not build the data layer interface (our Baltimore experiment has a real time data base but no API). I will probably just have an API to query real-time data in Javascript that could give out JSON files and a turn-key embedded script that could fit in any html page, with color coded icon for various averages.

For sending the device to Turkey, I suggest using services such as Aramex shop and ship that could allow you to have a PO box abroad (in the USA in particular). This can be a bit expansive but alleviate issues at customs.

For our current device, I will need at least 100 beta customer to be able to deliver the outdoor unit (after that I will need 6 weeks of lead time to produce). I am currently focusing on the indoor unit (see https://www.tropo.cc/), which should ship out in 8 weeks.
