It is ideal to detect if a human has moved in or out of the PIR sensor range. Connect VCC and GND to +5V and GND respectively. With the following example code, you can read out the sensor and control the on-board LED of the Arduino (connected to pin 13). With a PIR motion sensor integrated with an arduino, we can detect movement and program the arduino to turn a light on for a certain period of time once this motion is detected. PIR stand for “Passive Infrared”. Here we use PIR sensor and Arduino to detect the motion of a hand. The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. You won’t need all the parts, but I recommend that you at least have one piece that can show you when motion is detected, for example, the buzzer or LED. For this example, you need the following parts: 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 input and output. Every staircase is different!) So, it can detect motion based on changes in infrared light in the environment. In this example an LED will light up when movement is detected. The output of PIR motion detection sensor can be connected directly to one of the Arduino (or any microcontroller) digital pins. PIR Sensor provides a triggering pulse to arduino. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. Arduino is an open-source electronics platform based on easy-to-use hardware and software. You can use any of the Arduino board to make this project. PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range.
