WebMar 7, 2024 · A motion sensor (or motion detector) is the linchpin of your security system because it detects when someone is in your home when they shouldn’t be. A motion sensor uses one or multiple technologies to detect movement in an area. When a sensor detects motion, it sends a signal to your security system’s control panel, which connects to your … WebJan 31, 2024 · Active (microwave) motion sensors. Microwave motion sensors use microwaves to “see” what is happening around them. They send out pulses of microwaves, which bounce off of objects and reflect back to the sensor. If an object is moving, the measurement between it and the sensor will change, which trips the alarm. high clutterWebA passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view.
