What is the difference between photoelectric sensors and optical sensors?
A photoelectric sensor, or photo eye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are used extensively in industrial manufacturing. There are three different functional types: opposed (through beam), retro-reflective, and proximity-sensing (diffused).Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications, for example: Lamps that turn on automatically in response to darkness. Position sensors that activate when an object interrupts a light beam.
What are photoelectric sensors used for?
Photoelectric sensors use light to detect the presence, absence, or distance of an object. They often use the infrared spectrum of light, though visible light is also used.
How does proximity sensor work?
Without physical contact detecting the presence of objects is the purpose of proximity sensors. They work based on inductive, magnetic, photoelectric and capacitive properties of objects.
What is the light source used in most industrial photoelectric sensors?
The light source is typically a diode that emits either visible or infrared light. Other photolelectric sensors use lasers, which emit more coherent beams that scatter less and maintain their brightness over a distance. (see also the related link)

What are the main characteristics of microwave remote sensing and optical remote sensing?
Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.
What are Remote Sensing observational platforms?
The platforms that harbor remote sensing sensors (eg. cameras) are called remote sensing platforms. In earlier days, during military reconnaissance, pigeons attached with cameras were made to fly over areas of interest. In this case the platform is the bird. Balloons, airplanes and satellites that carry remote sensing sensors are examples of remote sensing platforms.
Where can you buy a UV sensing chip Like the UDT-455?
UDT Sensors, Inc.
What is applications of photoelectric effect in our daily life?
It is in the digital cameras, image sensors, and night vision devices that are widely used in the present world.
Is fiber optics and Fiber optic sensors are same?
No, A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors").
What is sensing process?
The sensing process involves collecting information or data from the environment through the use of sensors. Sensors detect and measure various physical properties such as temperature, pressure, light, or motion, and convert these into electrical signals that can be processed and analyzed to provide valuable insights and enable different applications or systems to respond accordingly.
What has the author Khanh D Pham written?
Khanh D. Pham has written: 'Sensors and systems for space applications IV' -- subject(s): Radar, Remote sensing, Congresses, Observations, Artificial satellites in remote sensing
What is a dead zone in sensors?
A dead zone in a sensor is the point where a sensor will not work. Ultrasonc sensors and specific optical sensors for example have measurement or detection ranges quoted as 30mm-300mm sensing. This means the sensor will not operate from 1-29mm or over 300mm.
How do Motion Sensing Lights Work?
Motion sensing lights use a passive system that detects infrared energy. These sensors are known as PIR (passive infrared) detectors or pyroelectric sensors. Human skin averages to be 93 degrees F, which radiates infrared energy in a wavelength that is between 9 and 10 micrometers. The sensors dectect quick movement of objects that radiate between 8 to 12 micrometers of infrared energy.
How does a sensor cature data?
It depends on what it's sensing. Thermistors are used to measure temperature. Other sensors depend on physical actions. Bump sensors are triggered when an object pushes the plate until the sensor is triggered.
