· Every object, with its surface temperature greater than absolute zero -273 0 C emits heat in the form of infrared radiation. Humans cannot see this radiation as the radiations are in infrared wavelength. But PIR Sensors detect these radiations and change them into appropriate electrical signals.

Also , it teaches us how to integrate PIR with Arduino.(This Tutorial is First in our series about Various types of Sensors. Follow Us to get know about other sensors …
· PIR sensors are commonly used in security alarms and automatic lighting applications. Technically, PIR is made of a pyroelectric sensor, which is able to detect different levels of infrared radiation. For example, Everything emits varied level radiation and the level of radiation will increase with the increase of the object’s temperature.
with a temperature above absolute zero (0 Kelvin / - °C) emit heat energy in the form of infrared radiation, including human bodies. A pyroelectric sensor has two rectangular slots in it made of a material that allows the. infrared radiation to pass. Behind these, there are two separate infrared sensor. electrodes, one responsible for producing a positive output and the other a negative ...
PIR sensor is a special type sensor which is usually used for security purposes. It detects the objects by reading the Infrared radiations emitted by the objects. Any object whose temperature is above absolute zero, emits radiation. This radiation is not visible to human eyes. The PIR sensor is designed to detect this Infrared radiation.

· When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. 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.
· PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, “Passive Infrared”, “Pyroelectric”, or “IR motion ...
· The output of PIR motion detection sensor can be connected directly to one of the Arduino (or any microcontroller) digital pins. If any motion is detected by the sensor, this pin value will be set to “1”. The two potentiometers on the board allow you to …

· PIR Motion Sensor Control LED. In this project you’re going to create a simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected. Connection. Build the circuit as below: Connecting PIR sensors to a microcontroller is really simple. The PIR acts as a digital output so all you ...
When the sensor is idle, there is no movement around the sensor; both slots detect the same amount of infrared radiation, resulting in a zero output signal. But 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.

Connect OUT to digital pin 2 on Arduino board. Connect GND with GND on Arduino. You can adjust the sensor sensitivity and delay time via two variable resistors located at the bottom of the sensor board. Once the sensor detects any motion, Arduino will send a message via the serial port to say that a motion is detected. The PIR sense motion will delay for certain time to check if there is a new motion. If there is no motion detected, Arduino …
· PIR sensors are really simple and easy to use as well as cheap motion detection sensor. The feature that it is easy to interface with any microcontroller makes it widely usable. This post is a simple one around how to interface any PIR sensor having digital output to the arduino board.
