Street lights can be made intelligent by placing cameras or other sensors on them, which enables them to detect movement (e.g. Sensity's Light Sensory Network, GE's "Currents", Tvilight's CitySense). [5] [6] Additional technology enables the street lights to communicate with one another. Different companies have different variations to this ...
The Leddar technology is like a light-based radar that sends very short light pulses of invisible light about 100,000 times per second to actively illuminate an area of interest. The sensor captures the light backscattered from objects (either fixed or moving) over its detection area and processes the signals to precisely map their location and ...
Single sensors may detect overall light levels. A 1-D array of photodetectors, as in a spectrophotometer or a Line scanner , may be used to measure the distribution of light along a line. A 2-D array of photodetectors may be used as an image sensor to form images from the pattern of light before it.
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
An intelligent sensor is a sensor that takes some predefined action when it senses the appropriate input (light, heat, sound, motion, touch, etc.). Description [ edit ]
Smart traffic lights or Intelligent traffic lights are a vehicle traffic control system that combines traditional traffic lights with an array of sensors and artificial intelligence to intelligently route vehicle and pedestrian traffic. [1] They can form part of a bigger intelligent transport system.
Via a three-colored light on top of the unit, a real-time sensor communicates indoor air quality – poor, moderate or good — with an Auto mode that will optimize an setting (1 through 3) based ...
Conceptual through-beam system to detect unauthorized access to a secure door. If the beam is interrupted, the detector triggers an alarm. A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are largely used in ...
