PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors ...

Code explanation of the Arduino PIR Interfacing. The code explanation of the code is as follows. The complete code can be found at the absolute bottom of the blog. const int pirPin = 5; This line ...

The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion of a human body by the change in surrounding ambient temperature when a human ...

This article is about making an intruder alarm using Arduino and PIR sensor. ... Circuit Diagram. Step 5: Getting Started With Arduino. If you are not already familiar with the Arduino IDE, don’t ...

Working of Dog Barking Security using Arduino. Make the connections as per the circuit diagram and upload the code to Arduino Nano. When powered, the PIR sensor detects the IR rays emitted from the ...

Arduino Motion Sensor – Circuit and Working. The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...
