(9 products)

PIR sensors work by detecting infrared light given off by a moving object or person that emits heat. They are typically used outside of a building either in security systems or automatic lighting applications, though are also be used indoors as part of a wider security system. PIR motion sensors are available in a range of options that can be either used as a standalone device or be linked up with a network. Look out for PIR detector features such as pet friendly technology to avoid unwanted alerts being triggered by animals.
