{"title":"PIR Sensor Light Fittings","description":"When a light fitting has an accompanying PIR sensor, this means that the light will turn on when motion is detected. PIR stands for ‘passive infrared’, meaning the sensor will passively pick up emitted infrared. This is accomplished by a pair of pyroelectric sensors that detects the infrared heat that radiates from people or objects. When one pyroelectric sensor detects a change in the infrared that the other pyroelectric sensor fails to pick up, this activates a switch that in turn activates the light.\r\n\r\nPassive infrared sensors can trace their roots back to the 1940s, when an alternative to microwave and ultrasonic motion detectors were in demand to cut costs. This became a reality in the 1970s, with PIR sensors making for a great option thanks to their small size, simple installation, cheap manufacturing cost, however, they did not become a popular choice outside of security alarms until the 1990s. Since then, the technology has become more reliable and the manufacturing costs cheaper, allowing for in-built PIR sensors in your light fittings without greatly impacting the cost of the product.\r\n\r\nOur catalogue of PIR sensor light fittings include bulkheads, floodlights, lanterns and wall lights in a variety of wattages, colour temperatures and finishes from leading brands such as V-Tac, MiniSun and Elstead Lighting. We also offer standalone PIR sensors to install on your existing light fittings from brands such Eterna and 4WiZ.\r\n\r\nPIR sensor light fittings are used in a host of general and specialist applications, with the two most popular uses being for security lighting and energy saving lighting. Some popular places to  find PIR sensor light fittings, both domestic and commercial, include: outside front doors, driveways, swimming pools, patios, smoking areas and much more.","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0908\/1487\/3927\/collections\/man-at-door-with-motion-sensor-light-activated.webp?v=1781617466","url":"https:\/\/shop.bltdirect.com\/collections\/pir-sensor-light-fittings.oembed","provider":"BLT Direct","version":"1.0","type":"link"}
