best way or method to activate LED lights from a maximum of hundred meters away. Answered
I have this project study on how to install, LED on a board as an indicator that a machine in the production line has fault. Since the production line has many machine and cell, its more convenient to install a wireless or activation through frequency.
The board will be installed at the Techinician station then a switch in the production line that will activate it. I'm here in the philippines and in our plant we use two power supply (110 v and 220v), its better if it the switch will be plugged to 110v.
Please advise for any information how to do it.
