This sounds vague, because it can have many, many possible answers (I hope), but I will accept any of them.

Basically, I want to demo a product, which has an eInk display (plus WiFi and BlueTooth), to a company in Singapore:

enter image description here

To give them an idea of how it can be used to display their data, I would like to display some Singaporean data, maybe population, or similar.

The catch is that I want it to updated every second or so, displaying the temperature wouldn't be much good as it rarely varies.

I don't care what the data is, so is it on topic to ask for some Singaporean data which changes every second or so and has a gratis HTTP(S) API? I would like something to grab their attention and get them wondering how we can use this (cheap) device.

    In a demo, would be cool to have a temperature and/or CO2 sensor. That way you could exhale on the sensor or hold it in your hand and watch the display update – philshem Nov 20 '19 at 15:34
  • Not exactly Singapore related :-) but a good suggestion. Upvote – Mawg says reinstate Monica Nov 20 '19 at 20:26

Singapore offers an API for pollution levels (among 13 other real-time APIs)

try it in their docs page: https://data.gov.sg/dataset/psi

or with curl

curl -X GET "https://api.data.gov.sg/v1/environment/psi" -H  "accept: application/json"

or with the browser: https://api.data.gov.sg/v1/environment/psi

(not sure if any of these 14 real-time APIs are actually enough real-time)

  • I doubt that pollution levels change quickly enough but have long thought that an air pollution device would sell well. I already saw that link to the real time APIs and thought of maybe something with taxis or parking spaces; those will certainly change on a per second basis.

  • The Carpark Availability seems like it will change often enough to be useful – Mawg says reinstate Monica Mar 27 '20 at 21:11

    In the end, I had a lot of fun mapping the current locations of available taxis. – Mawg says reinstate Monica Feb 27 at 10:55
