The project proposes a monitoring and alarm system with a safety lock.
The sensors that constitute it are three ultrasonic sensors, which by
rotating through a servo measure the surrounding environment at 360
These have been set in such a way that when they detect objects
smaller than a distance of 70cm they activate a led. While for a distance
of less than 50cm they activate a Buzzer.
On the other hand, when an object approaches more than 10 cm, it
activates the second servo making it rotate from 0 to 90 degrees and
blocking the circuit.
This system was designed for the monitoring and protection of objects
on display.
