Hi Guys,

for a installation I was using proximity sensors (sharp) but no i need to replace them (12) with lightbarriers, since the distnce isn't important anymore but they have only to be triggered.
I was looking for already ready assambled light barriers but they seem still to be quiet pricy.

Can somebody recommend something which works like a light barrier, so it can detect if somebody passes by and works as well easily at night.

Thanks!
