Is it possible to have the environment temperature displayed as an overlay on a live camera feed? I'm sure this would require several additional components, for example, I'd need a device that reads the active temperature and then (likely) another device that can take that data and overlay it onto a camera.
I'm sure a quick way around this is to simply install a temperature gauge at that site and put it in an area that is visible by the camera, but I'm curious if this is something that others have done/seen (my original question, above).
