Motion sensors and Motion detectorsSteinel Motion Light Sensor-Vacker Africa

Motion sensors are the most widely used category of automation sensors and is equally utilized in industrial and commercial applications. The reason for wide usage is that these are the essential part of energy conservation in commercial, residential and industrial applications and the installation is extremely simple enough to be carried out by normal technicians. These are also known as movement sensors and movement detectors. Such sensors are also an integral part of Home automation and office automation systems which can be integrated into an entire system or individual units or a section of the room, corridor etc. as per the customer requirements. These are available in latest Automation protocols such as KNX, Bacnet etc. for integrating into an entire building management system. Ultrasonic sensors and Infrared sensors are the most commonly used technology for detecting motion.

As obvious from the name, these are also known as motion detectors are used to detect motion. The motion thus detected may be that of human beings, machinery parts, mechanical parts etc. depending on the application. The basic principle is that it will be constantly monitoring a certain area or a linear path. If any movement happens in this area, the sensor will detect the same and an output signal will be provided to other connected circuitries and instruments to carry out any related functions. These are also called Motion sensor switch since the sensor is only carrying out a switching action. Different models for indoor and outdoor applications are available.

How motion sensors work?

All motion sensors work by detecting an input and providing an output. Motion detectors use different technologies for detecting motion. All such sensors have a transmitter and receiver. The transmitter constantly emits different types of waves based on the technology used and the waves are received back at the sensor after a time delay. Various parameters between transmission and reception are analyzed by the motion detector which determines whether a motion has been detected.

All of them will generally have adjustable sensitivity and delay timing. Sensitivity setting is for adjusting the sensitivity of movement detection. If most sensitive setting is selected, minute movements will be detected. Delay timing is adjusted to set the delay in switching after a movement stops. Eg. if a delay period of 60 seconds is programmed for the motion sensor, the lights will be switched off after 60 seconds from the last detection of a motion. These particular types are also called Motion sensor lights
