How PIRs Work | PIR Motion Sensor | Adafruit Learning System

Jan 28, 2014· PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.

Arduino - PIR Sensor

Arduino - PIR Sensor. PIR sensors allow you to sense motion. They are used to detect whether a human has moved in or out of the sensor’s range. They are commonly found in appliances and gadgets used at home or for businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

Full Form of PIR Sensor | FullForms

What does PIR mean?. A Passive Infrared sensor (PIR sensor) is an electronic device which can detect levels of infrared radiation from objects in its field of are basically made of a pyroelectric sensor which can detect levels of infrared radiation. All objects above absolute zero emit energy in the form of radiation and if the body is hotter it emits more radiation.

Passive infrared sensor - Wikipedia

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved.
