Pyroelectric Infrared PIR Motion Sensor Detector


Motion sensor no more remains an exclusive features available to the researchers only. PIR motion detectors have made it possible for domestic users to benefit from this impressive technology. Pyroelectric Infrared PIR Motion Sensor is an incredible addition to the generation of IPR motion sensors.

How PIR Motion Sensor (Pyroelectric) 

As the title suggests, a PIR sensor detects motion of a living thing. Conventionally, the technology had remained expensive and rarely available as a commercial product. Things have changed over the years and we now have much smaller, more effective and inexpensive PIR motion sensors. The best thing is that a PIR sensor works with low-power and keeps serving for years without showing any signs of wear and tear. Passive Infrared motions sensors contain pyroelectric sensors supported by electric circuits, capacitors, and resistors.

The basic mechanism is same as of a heat sensor but the methodology is modern involving complex circuitry and computation. The device is capable of sensing heat emitted by the living things. You can use these devices for stealth camera (just like biologists do to track animal’s activities). It’s all fun and education and feels nice to add a magnificent feature to your system. Something you could show to your friends over and over again. If you haven’t tried it before, this is the time to purchase one!
