How Does a Motion Detector Work?
- When people talk about motion, they are generally referring to how fast an object goes over a determined length of time
- In physics, there are different types of motion, as well. And motion can be created by applying force to a given object
- The force causes particles to accelerate and essentially change the area around them. How much something weighs can affect how fast or slow the object can go
- Much the same way a radio antenna can emit or receive radio waves, a motion detector can send out a signal to know if there are objects nearby
- Basic Motion Detectors
- There are different types of motion detectors, but they all basically work the same way
- Motion detectors are made to register certain information in the air created by objects that speed up or slow down
- It compiles those signals into data that must be reflected back into a sensor inside the detector itself. There must, however, be sensors placed elsewhere for signals to get sent to a detector
- Using a series of either mirrors or electronic sensors, a basic motion detector, after receiving a signal, will emit a signal or pulse to a nearby computer or camera
- In some motion detectors, the whole process takes less than a microsecond
- Microwaves, Radar, Infrared and Ultrasonic Motion Detectors
- Motion detectors all receive and measure information differently
- A microwave or radar motion detector works the same way as a radar gun
- When a police officer points a radar gun at a moving object far away, that object sends back certain information, which registers in the radar gun as a series of data that is interpreted as signals. Waves have certain ways of behaving, depending on length and size, for example
- Microwave motion detectors use waves that are generated along an electromagnetic spectrum, typically radio waves
- An infrared motion detector can detect changes in movement by using light. It also can detect changes in temperature
- Just like electromagnetic waves run along an electromagnetic spectrum, light waves have their own spectrum
- Heat and ultraviolet rays are two types of invisible light waves that can be measured by numerous types of infrared sensors
- Ultrasonic motion detectors use physical and sound waves, rather than mechanical or electromagnetic waves, like the microwave or radar motion detecto
