In this video, I made a simple alarm using the relay module. This security alarm is very, very simple to make, but its performance is very high. The way it works is that a wire is the link for the relay to be active, and when that wire is cut, the relay is deactivated and the siren or projector or... is activated to inform you of the presence of the thief.
These types of alarms are mostly connected to the entrances of every room or place, close to the ground. So that when a person enters the room or place from the entrance (due to not seeing and not noticing this thin wire), he steps on the wire by mistake, causing the relay connection to be disconnected and the siren or projector to be activated.
Join me to take a look at how it is made and enjoy its construction and technology.
