Motion detector lights work by using sensors, such as infrared or microwave sensors, to detect changes in the environment caused by movement. When movement is detected, the sensors trigger the light to turn on and illuminate the area.
Motion sensing lights work by using sensors, such as infrared or microwave, to detect movement within their range. When movement is detected, the lights are activated and provide illumination in the area. This helps to save energy and increase security by only turning on when needed.
A metal detector can detect all types of metal....depending on in what type of soil it is in.
the function of a diode detector is to detect stuff

When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.
Motion detector lights are outdoor or indoor lighting fixtures equipped with sensors that detect movement within a specific range. When motion is detected, the lights automatically turn on, providing illumination for security, convenience, or safety. They are commonly used in residential and commercial settings to enhance visibility and deter intruders. These lights can be activated by various types of sensors, including passive infrared (PIR) and microwave sensors.

A presence detector is a device that uses sensors to detect the presence of a person or object within a certain area. These detectors are often used in smart home systems, security systems, and lighting control to automatically activate or deactivate devices based on the presence of individuals.
-- If the detector is designed to detect wave characteristics, then light exhibits all the characteristics and behavior of a wave when it encounters that detector. -- If the detector is designed to detect particle characteristics, then light exhibits all the characteristics and behavior of a particle when it encounters that detector.
The motion detection device was invented by Samuel Bagno in the early 20th century. He developed the first motion detector to detect intruders by sensing their movement.
