Motion sensors are often used in indoor spaces to control electric lighting. If no motion is detected, it is assumed that the space is empty, and thus does not need to be lighted. Turning off the lights in such circumstances can save substantial amounts of energy. In lighting practice occupancy sensors are sometime also called “presence sensors” or “vacancy sensors”.

Motion can be detected by measuring change in speed or vector of an object or objects in the field of view. This can be achieved either by mechanical devices that physically interact with the field or by electronic devices that quantifies and measures changes in the given environment.

Motion detection devices function by detecting physical movement based on changes in speed or vector of an object within a given field. Motion detection devices offered by Select Controls include motion switches and motion sensors. These devices are used to sense and monitor vibration, pressure, speed and presence, and work in conjunction with one another.

Motion detection devices, motion switches and motion sensors can be used in a wide range of applications and serve many functions. A variety of contact, damped and response options are available. Select Controls offers quality and dependable monitoring devices that are suitable for commercial, medical, marine and military requirements. Speed, synchronization, proximity and function configurations can be tailored to your specifications.
