There are two main types of motion sensors: passive and active. To detect motion, the majority of outdoor lighting systems use passive sensors. You can also read more about motion sensor outdoor lighting through twilightsolutions.com/services/commercial-lighting

(i) Active sensors – emit energy to detect movement within its range. The energy is reflected back to the object when it comes within range of this energy emission. This triggers a response. This response can be anything from turning on lights, setting off alarms, or opening doors.
(ii) Passive sensors – also known as Passive Infrared Sensors or (PIR), detect infrared energy. Infra is the color below which a human can perceive visual information. Red refers to the lowest visible color.
Passive sensors are able to detect sudden changes in infrared energies and measure the wavelengths in micrometers. Infrared energy is emitted by the human skin in the range of 9-10 micrometers.
The installation of motion sensor outdoor lighting is a simple project that anyone can do. These are some simple but essential points to remember if this is your first project in home improvement or your first experience with outdoor lighting.
It is essential to turn off power to your outdoor lighting kit if it requires that it be connected to a power source. You can make it even more secure by turning off the power to your entire house. Also, you should cover the fuse box with electrical tape or masking tape (with instructions to turn the power off) so that it doesn't get accidentally turned on again.
