DIY Light Barrier Alarm System With an Industrial Grade PLC (Controllino)

In this project I will be showing you how I combined a PLC (the Controllino) with a light barrier, a siren, a reed switch and a stroboscope light in order to create a truly robust working alarm/security system that will scare off intruders easily. Let's get started!

The video gives you all the information you need to create your own light barrier alarm system. During the next steps though I will present you some additional information.

You can get most of the components from the home improvement store:

- distribution box

- M20 installation conduit

- pipe clamps

- WAGO terminals

- Wall plugs + screws

- NYM Wire, all the other wires,.....

You can also find out how to build the stroboscope light (with parts list) here: https://www.instructables.com/id/Make-Your-Own-LED...
