in the device there is a motion control feature which also has the ability to detect facial expressions..:D
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.
An accelerometer is a device used to detect motion by measuring the acceleration of an object. It can be found in smartphones, fitness trackers, and automotive airbag systems, among other applications.
Geiger counter.
A magnetic device use to detect the revolutions of an entity.
A magnetometer is a device used to detect changes in the strength and orientation of magnetic fields. It is often found in devices like smartphones to provide functions such as compass directions and motion sensing.

The first motion detector was invented in the early 1950s by Samuel Bagno. He developed a device that could detect motion using a technology called ultrasonic waves. This early version of a motion detector paved the way for the more advanced versions we use today.
You can use a motion sensor or a tracking device that can detect even small amounts of motion. Another option is to observe changes in its surroundings, such as its position or orientation in relation to other objects. Alternatively, you can measure its speed over a longer period of time to detect any subtle movements.
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example.
No. There are not machines that can detect motion sensors. You may be able to detect the sensor rays through special lighting, but the beams are normally invisible.
Laser sensors are generally used to detect motion. They can be used as a safety device to protect something like a car hitting a wall. They can also be used to detect measurement and alignment and are widely used in medicine and industry.
