About the PIR Detector:
- A Passive InfraRed sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR-based motion detectors (see below). Apparent motion is detected when an infrared source with one temperature, such as a human, passes in front of an infrared source with another temperature, such as a wall
- All objects above absolute zero emit energy and is in reference to what is known as black body radiation. It is usually infrared radiation that is invisible to the human eye but can be detected by electronic devices designed for such a purpose. The term passive in this instance means that the PIR device does not emit an infrared beam but merely passively accepts incoming infrared radiation
- "Infra" meaning below our ability to detect it visually, and "Red" because this color represents the lowest energy level that our eyes can sense before it becomes invisible. Thus, infrared means below the energy level of the color red, and applies to many sources of invisible energy
- In a PIR-based motion detector (usually called a PID, for Passive Infrared Detector), the PIR sensor is typically mounted on a printed circuit board containing the necessary electronics required to interpret the signals from the pyroelectric sensor chip
- The complete assembly is contained within a housing mounted in a location where the sensor can view the area to be monitored. Infrared energy is able to reach the pyroelectric sensor through the window because the plastic used is transparent to infrared radiation (but only translucent to visible light)
- This plastic sheet also prevents the intrusion of dust and/or insects from obscuring the sensor's field of view, and in the case of insects, from generating false alarms
Types of Motion Detectors:
There are many kinds of motion detectors, and they're found in many places. Although the service they supply is very simple and straightforward, they utilize sophisticated means, including infrared technology. Most people have at one time or the other wandered within the range of a motion detector. When you approach the entrance of a garage or house door in the dark, and suddenly lights come on, the seeming magical illumination is due to a motion detector
What Are Motion Detectors?
As the name implies, motion detectors detect movements within the range of the equipment. Motion detectors vary in size and they use many kinds of technology to perform their functions. They do not run like machines; they are passive instruments that monitor motion of any kind. Often installed with security alarms systems and other applications, they are widely used in both residential and commercial buildings, and for other security-related operations. Any motion detector usually contains two elements: a device (or sensor) that detects motion, and one that relays the information that movement is present, typically a light.
- Kinds of Motion Detectors--Infrared: There are several kinds of motion detectors, and one of the newest employs infrared technology, appearing on the stage during the 1980s. The state of the art in the motion detector technology, infrared detectors rely on a laser as their sensor to detect motion. Infrared sensors only perceive and relay information relative to the movements of living organisms because they read body heat in objects appearing within their range
- Microwave Motion Detectors: All motion detectors serve the same purpose through different means. The microwave sensor emits microwave energy, filling the area in its range. When any object appears within range and disturbs the microwave energy field, the detector immediately sends signals to remote equipment about the motion
- Ultrasonic Motion Detectors: Ultrasonic motion detectors are used in specific situations, for instance, to measure level of liquid contents in a tank. They are still widely in use today, particularly in harsh environments where traditional motion detectors may not work. There are variations of ultrasonic motion detectors. In some of these systems, the sensor and the controller are built into one unit. In others, the sensor may be placed at a remote location but connected by wire to the controller
- Digital Motion Detector: Digital detectors are very accurate. The technology is typically used in industries such as railroads. They are used to monitor oscillator signals on a continuous basis, and issue warnings to railway crossings when a train is approaching. The oscillator frequency is normally held constant, and when changes in frequency are detected, a signal indicating the change is sent
