Security Alarm using HC-SR501 PIR Sensor and Arduino
0 Comments
In this Arduino tutorial, we are going to learn how to use a motion sensor to sound a piezoelectric buzzer. The motion sensor used here is a PIR sensor which stands for Passive Infrared Sensor. This is great for an intrusion detection circuit or burglar alarm circuit. Whenever the motion sensor senses movement the piezoelectric buzzer will...
