A sensor is a device that translates observations from the physical world into electrical signals. These electrical signals can then be read and translated into other electronical devices, such as computers. The readable output is also known as data. Sensors can measure physical properties, such as temperature, pressure, light intensity, force and flow. Sensing or sensor technology is the way in which sensors are integrated into various types of technological systems or sensor networks.
There is a wide range of technological systems that all serve different purposes. For example, video or surveillance cameras (CCTV) are utilized to monitor various areas from a distance or register movement. Also, sound detectors, heat sensors or other forms of audio-visual technologies are integrated and applied in for example Security Operations Centres, surveillance, Smart City innovations or Remote monitoring.
