Advanced burglar alarm

Burglar alarms are part of technical protection, very important for securing residential and commercial buildings. They combine various components, such as sensors and photo-emitting diodes for warning, to detect and react to a burglary attempt. The work shows how a burglar alarm system with an ultrasonic sensor can effectively detect and react to unauthorized access. The main focus is on the integration of different components using the Arduino platform, thus demonstrating how a relatively simple technology can significantly increase security.
