How do these talk with the outside world? Do you need to attach them to your own internal WiFi?

Yeah. Currently we piggy-back on a locations wifi. Relatively low upstream data (37kb / 90secs).

We've considered things like Helium. Eventually centralizing the network will be good but for now, wifi's cheap and available.

This looks awesome! Would love to know ahead of time how crowded my local coffee shop is before I packed up to work there.

If this is the indented use case what purpose the coffee shop have to add one? If in most cases it'll only discourage customer attendance. To be a member of the queue of an establishment can carry some of the social status of that establishment itself. This is a primative notion yes, but fairly ingrained culturally. As businesses often judge their prestige by the length of the queue to enter.

Too long of a queue could discourage customer attendance as well, as people may not want to wait a long time, no matter how prestigious the business is. In addition, a lesser-known business could use lower wait times as a competitive advantage.

What really matters, in my opinion, is whether having a long line during certain peak times generates more revenue for the business (by being able to charge more, or by gaining attention due to its long queues) or whether providing a faster and better customer experience with shorter wait times does (and perhaps more customers during non-peak times)

Whether one is better than the other may depend completely on your business. Also, I'm not sure this technology forces you to publish your current density information. You could simply use the information for business intelligence gathering and for providing promotions during non-peak times.

>> "After adding Density, we saw as much as a 950% increase in site traffic to supported locations. Our users love it." - Darren Buckner, Workfrom CEO When I use google maps, it shows me how busy various roads are and it also chooses the fastest route based on how fluid the traffic is. Seems like google maps is just observing the world and making decisions based on those observations. Now I was wondering, what if all…

I thought Google Maps used the Android phone location to know the busy road?

Does this use PIR out of curiosity, or are you using an emitter, receiver in one package.

We’re using infrared sensors. Both the emitter and detector are on a single sensor, so we only affix our hardware to one side of a doorframe. This is different than break beam which requires hardware on each side of a door.
