What are they?
PIR (Passive Infrared) sensors are passive devices that use infrared to detect moving objects without emitting energy. They work by detecting changes in temperature from a “standard” value caused by people or objects entering the monitored area.
How do they work?
PIR sensors feature pyroelectric materials that generate electrical energy when exposed to the heat of infrared radiation. Each PIR sensor is made up of two slots, both made of pyroelectric material, each with an infrared electrode. Under normal conditions, both slits receive the same amount of infrared radiation. When there is a change, one of the slits receives more radiation than the other, generating the first output signal. If the moving object or person continues to move, the other slit is also “altered”, generating a second signal.
What are the advantages?
PIR sensors offer numerous advantages, including compact size, low cost and low energy consumption. They are highly performing and require little maintenance. Furthermore, they can be easily integrated with various video surveillance systems, alarms and smart video intercoms.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
