Proximity sensor, input source switcher

post #1 of 2
Thread Starter 
Hi all,

Does anyone know of anything on the market that would automatically sense when a person is in front of an LCD screen and would in turn switch the screens input to a different source?

For example, when no one is in front of the screen it would play a video loop on HDMI 1, but as soon as a person is in front of the screen a sensor would 'see' them and switch the input to HDMI 2, which is a PC desktop.

Maybe it is not the actual LCD screen that is switching inputs, perhaps it is a separate switching device that the sensor is plugged into...not really sure, but I have seen a setup like this but unfortunately was unable to get any info.

Any ideas?

I built a device using a Teensy USB develepment board and a PIR sensor to automatically switch on my LCD movie poster display whenever movement is detected, it also turns the display off if no movement is detected for a period of time. I'm sure a similar concept could be used to switch the inputs instead of power. you'd probably want to set up an IR emitter to blast the codes to change inputs instead of using the relays to simulate button presses like I did though.
