Hi guys. I have been working on my project. Something that could detect incoming intruders in the house. is there a way to make an optical sensor to detect as far as 1m? I looked up some of the sensors in the market but a lot of them can only detect as far as 2mm. Or is there a better way? The sensor output should be able to activate a relay in so the output should be approximately 6v min.
Thanks.
i think this works but it functions as a sound/tone detector or something.
