How HC-SR501 PIR Sensor Works & Interface It With Arduino

Wiring – Connecting PIR Sensor to Arduino UNO. Now that we have a complete understanding of how PIR sensor works, we can begin hooking it up to our Arduino! Connecting PIR sensors to a microcontroller is really simple. The PIR acts as a digital output so all you need to do is listen for the output pin to flip HIGH (Motion Detected) or LOW (Not Detected). Power the PIR with 5V and connect ...

Tutorial: How to use the HC-SR505 PIR sensor with the Arduino

30/08/2017· Pin layout used in this tutorial to wire the HC-SR505 PIR sensor to the Arduino Uno. In order to wire the SR505 to the Arduino, you need only three wires. The SR505 has three pins which are marked on the back: “-“, “OUT”, and “+”. First, make sure that the SR505 is provided with enough voltage: One of the Arduino’s GND pins must be connected to the SR505’s “-” pin. Next ...

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

23/03/2018· 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 motion sensor. Depending on the PIR motion sensor ...
