Hello all, I am new to the forum.
I have a project I am working on which requires me to create a 3 inch by 3 inch square area that when a green laser light is pointed anywhere within the 3 by 3 square a signal of 5 volt min to 24 volt max will be sent to a plc.
Is such a circuit possible?
If so could someone explain to me how this can be achieved.
I have tried using the circuit shown on Robs Robot room which uses photodiode's but would not work in sunlight, indoor light, and dark.
This is a requirement of what I'm trying to achieve.
Any help would be greatly appreciated.
Regards,
Wayne
