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!

Step 1: Watch the Video!

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.

Step 2: Order Your Components!

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...
