How to Build an Arduino-Powered Motion-Sensor Alarm ...

Mar 23, 2018· The sensor gets activated whenever you are within a 6–7 m of the radius of the Arduino PIR motion sensor. After that, the piezo buzzer will begin to make an alarm sound, and the string "Intruder detected" gets printed on your serial monitor. The sensor outputs a LOW signal (0V) after a minute when you are no longer near the radius of the PIR ...

Jul 27, 2017· The sensor outputs a 5V signal for a period of one minute as soon as it detects the presence of a person. It offers a tentative range of detection of about 6-7 m and is highly sensitive. When the PIR motion sensor detects a person, it outputs a 5V signal to the Arduino. Thus, an interrupt on Arduino is triggered.

Arduino with PIR Motion Sensor | Random Nerd Tutorials

Aug 18, 2014· The PIR motion sensor is ideal to detect movement. PIR stand for “Passive Infrared”. Basically, the PIR motion sensor measures infrared light from objects in its field of view. So, it can detect motion based on changes in infrared light in the environment. It is ideal to detect if a human has moved in or out of the sensor range.
