Sensor filter

[BNNorman]

Would it be possible to filter the map by device name? This would allow is to show just HCCxxxxxx sensors. Also, if we include pax counters we would then be able to just show those. This needs more discussion , perhaps layers might be the way forward?

Absolutely, I think that's perfectly do-able. Updating the heatmap accordingly might be more difficult though.

I'm not sure what you mean by "pax counters" though. Could you elaborate please?

As we acquire more sensors, it might be worth building a filter button that brings up a configurable pane.

Pax counters count wife and bluetooth devices as a location hence crowd density. I'll bring mine on thursday.

Not sure I understand, @BNNorman. Yeah, a demo would be great!

[BNNorman]

Ok, a pax counter monitors wifi and bluetooth signals. Most people have a mobil phone so you can deduce the number of people from the number of signals.

If you have several scattered around you can produce a heat map showing where most people are. Many applications including crowd monitoring, eg build up of people in a given location.

Ah, I see. That does sound useful, but I'm not sure how that relates to measurements / air quality? Are you aiming to use air quality web to display pax counter readings? It's certainly possible, I guess. Just need to add a definition to the DB.

At some point I should review the default colour gradient too.

[BNNorman]

Need to talk to rob but the database can cope with different types of measurements. Also, although the web page is biased towards aq it could cope with any variable type. Question is " should it allow mixed concepts or not". Will talk at meetup.

[sbrl]

Yeah, it can. Good idea - speak to you then.

[BNNorman]

Aq.connectedhumber.org now shows sensor map but the color scale is still there.

[sbrl]

Yeah, I haven't hidden that yet. Is that just for certain types of reading, @BNNorman?

[BNNorman]

No, its for everything because it implies that our readings have meaning and we should leave it to the reader to interpret the readings to avoid any clashes with the hcc air quality officer. (For the time being)

[sbrl]

I see, @BNNorman. That a bit frustrating, because it actually took me a few hours to implement that gauge in the first place. I'll look at removing then, I guess, but I'm not entirely sure that it does indicate that our readings have meaning.

It feels like people are trying to infer things incorrectly here - perhaps an explicit message would be a better approach.

[BNNorman]

I agree your sentiment. It feels a bit like a brexit vote in parliament. The gauge , as it stands,would only apply to air quality.

Join the club. I've spent hard cash on hdw which was never used because of design changes over the past 8 months.
