Davis AirLink Professional Air Quality Sensor (7210UK)

[beteljuice]

It also shows the problem with these optical sensors and 'smoke' - the AQI is for grit and dust !

From what I have read, they are designed for smoke and similar particulates.

The beteljuice plaything (Davis version) now correctly labels "Nowcast" and uses that value for the "widget"

zip link at bottom of page for the adventurous ...

Looks great, hav it sitting here for a play.... http://weather.inverellit.com/al/davis_example.php

Just need a little help on replacing the URL for my own data.

Code: Select all

$useOwnJSON = "http://wareham-wx.ddns.net/v1/current_conditions"; // url of 'donor' json file

I presume I meed to poke the AirLink with a bit of code that gets the JSON strin & processes it for me to then upload?

Can't find mention of that in the thread.

Phil.

the beteljuice is totally ignorant of how to 'get at' the sensor.

Some discussion is half way down the previous page

Have just received the Airlink and have it integrated easily into the Cumulus MX software - thanks to everyone responsible for making that happen. Very impressed so far. Wondering if there is any chance the air quality results will be integrated into the graphs at any point - would be good to see the changes in air quality in graphical form.

I was finally able to do this by using port 8080 as the incoming port to the router, then using port 80 as the outgoing port to the AirLink. This works great now. I'm guessing that perhaps my ISP was blocking incoming traffic on port 80 since 8080 works fine.

I've tried Betel's page with $useOwnJSON = "http://MyPublicIP:8086/v1/current_conditions" & I get "No Valid Data Found".

if I open http://MyPublicIP:8086/v1/current_condition in a browser I see this string,

Code: Select all

{ "data": { "did": "001D0A1001B0", "name": "Inverell", "ts": 1604710386, "conditions": [{ "lsid": 361501, "data_structure_type": 6, "temp": 76.3, "hum": 34.9, "dew_point": 46.6, "wet_bulb": 54.2, "heat_index": 74.9, "pm_1_last": 0, "pm_2p5_last": 0, "pm_10_last": 0, "pm_1": 0.00, "pm_2p5": 0.00, "pm_2p5_last_1_hour": 2.00, "pm_2p5_last_3_hours": 2.00, "pm_2p5_last_24_hours": 2.00, "pm_2p5_nowcast": 2.00, "pm_10": 0.00, "pm_10_last_1_hour": 2.58, "pm_10_last_3_hours": 2.58, "pm_10_last_24_hours": 2.58, "pm_10_nowcast": 2.58, "last_report_time": 1604710386, "pct_pm_data_last_1_hour": 36, "pct_pm_data_last_3_hours": 12, "pct_pm_data_nowcast": 3, "pct_pm_data_last_24_hours": 1 }] }, "error": null }

Presuming it needs more processing.

If you view-source, debug is 'on'

<!-- module betel_AQ_davis.php => ws_curl (715): Error codes:Failed to connect to 203.129.24.45 port 8086: Connection refused -->

[Phil23]

Can't see why the connection is refused.

Just tried the IP/Port from a remote site & I can see the data stream.
So it's not as if it's a maximum connections exceeded.

[beteljuice]

Works for me Using phil's data

Double check your entire url code line for errors ...

BetelJuice Enjoys a good Taunt....

I'm buggered if I can see it; & Can't even relate it to Aussie 4pm Saturday Beers; only one on the board so far....
Pasted straight out of NotePad++, & can't identify a single wrong character....
Must be loosing my mind.

[beteljuice]

Not a taunt ...

I confirm your file is exactly as the one I have working

It needs someone with better knowledge than me I'm afraid ....

[HansR]

I can see the AirLink data, no problem (http://203.129.24.45:8086/v1/current_conditions).
So I would suggest you check your IP routing @Phil. Somewhere on he way it is blocked inside your local net.
