What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
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.
Which type of energy is it when we feel heat from the sun?
Radiant energy (light) - the heat you feel is "infra red" radiation. Your eyes can not see this wavelength of light but there are sensors (thermal sensors) in your skin that can feel it.
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 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 the advantages and disadvantages of a sensors?
The advantages of light sensors is that they are really good security systems. The disadvantage of them is that they're really easy to set off.
Where are light sensors used?
light sensors are used in cars, televisions and computers. there are different types of light sensors.
What are the disadvantages of sensors?
They can fail if the system has a malfunction.
What do light sensors do?
Light sensors measure the number of photons or the energy of light hitting the sensor.
What do light sensors measures?
Light sensors measure the number of photons or the energy of light hitting the sensor.
What are light sensors used for?
Light sensors are devices that are designed to detect light. There are several different types and styles of light sensors, each of them unique and having their own specific and useful uses.
Advantages and disadvantages of infrared?
Advantages-Many things are controlled by infrared. sensors are invisible to the naked eye and are very reliable. Disadvantages- Most infrared sensors must be lined up or they will not work
What are stop light sensor?
Stop light sensors are a loop of wire that is buried in the pavement and controls the traffic light. The sensors are able to detect the traffic that is waiting at the light.
How sensors are used?
Sensors are used to detect things, such as motion, light, or color.
What are the advantages and disadvantages of using sensors?
It's situation dependent.
What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
What you mean by camera sensors?
Camera sensors record the image when light hits it. http://www.digicamhelp.com/camera-features/camera-parts/sensors/
