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.

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.
On what factors does photoelectric current depends?
photoelectric current depends on intensity of light used
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 type of sensors used in airplane?
type of sensors used in aeroplanes
What types of alarms are there?
Many. For consumers, there are primarily photoelectric sensors and ionizing sensors. There are many versions that include the alarm with the sensor in one unit and many versions that have smoke sensors remotely distributed and connected to one or more centralized control panels. Commercial smoke alarms include more sophisticated air-sampling sensors, in addition to those available to household consumers.
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.
