My cousin has children that stay too close to the screen whenever they are watching tv. He's asking if we can shutdown the tv if there is someone too close to it.
So, is it safe (especially for tv) to just use a proximity sensor with a relay (no arduino needed maybe?) to shutdown tv? or is it better to use an IR emitter and send a shutdown command? any other ideas?
I think a hc-sr501 module and a relay could be enough even without an arduino :
hc-sr501
Operating Voltage Range: 5 V to 20 V
Power Consumption: 65 mA
TTL Output: 3.3 V, 0 V
Lock Time: 0.2 sec (adjustable)
Sensing Range: <120°, within 7 meters (adjustable)
Temperature Range: -15° C to +70°
A lot of the larger Sony TV´s have this built in they call it distance alert - it doesn't turn the TV off it just switches to a warning message and sounds an alarm. They use it to scare toddlers away from the TV hopefully stopping them from pulling it over onto themselves. Or you could just fix the TV down.

That's cool

I thought concern about sitting too close to a TV was an "old wives tale".
On the other hand watching TOO MUCH TV ....

Me too, i even remebre i watched a tv emission talking about this subject (mythbuster?), and tv was innocent

Or just good old fashioned discipline.
I only got asked a couple of times when I was a kid. Third time was generally a clip round the ear. I soon got the idea, and don't think any less of my parents because of it

Hey. Thanks for that. The problem is that my cousin (usually very strict) works abroad and comes home once a week, and his two sons are very active/foxy? and his wife can't handle that alone
