Motion Sensors
A motion sensor (or motion detector) is an electronic device that is designed to detect and measure movement. Motion sensors are used primarily in home and business security systems, but they can also be found in phones, paper towel dispensers, game consoles, and virtual reality systems.
PIR Sensors
The abbreviation PIR stands for “passive infrared.” Infrared sensors only detect heat signatures.Something is moving across the sensor’s field of vision,that causes the light to turn on.The heat signature diminishes exits the sensor’s area of vision,the sensor returns to normal and shuts off the light.
