Motion detector - Arduino project
Arduino Projects - Motion detector : Security lighting system by Riana Galiaskarova. The purpose of this idea is to create a building security lighting system that not only turns on lights when motion is detected, but also produces a sound alarm to notify the security of movement. This adds another level of warning and security.
To control the real lights the design employs an Arduino board, a PIR motion sensor, an LED indicator light, and a buzzer.
When the PIR sensor detects motion within its detection range it sends a signal to the Arduino. The Arduino then activates the LED light as a visual indicator and the buzzer that creates an alert sound. All of this occurs within seconds of motion being sensed.
The sound alarm which provides an early warning, and the ability to manage and monitor specific zones in the building are advantages above an idea of a public area lighting system. The advantages over a smart home lighting system are cheaper cost, simplicity and reliability (because there are fewer electronic components that could fail).
