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

About: Awesome Electronics Tutorials, Projects and How To´s

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!
