An optocoupler is a piece of electronic hardware that connects two independent electrical circuits via a light sensitive optical interface.In a number of applications, the optocoupler is an electrical component that serves as an interface between low voltage digital or control circuits and high power electronic devices.
To put it another way, transformers employ electromagnetic coupling to separate the primary input voltage from the secondary output voltage, which is achieved by the magnetic flux rotating through their laminated iron core.
An optocoupler, also known as an opto-isolator, is made up of an LED that generates infrared light and a semiconductor photo-sensitive device that detects the infrared beam.
Both the LED and the photosensitive device are enclosed in a light-tight body or package.An optocoupler is also known as a A light emitter, or LED, and a light sensitive receiver, which can be a single photo-diode, photo-transistor, photo-resistor, photo-SCR, or photo-TRIAC, comprise an optocoupler, also known as an opto-isolator.
The basic mechanism of an optocoupler is simple to understand. The photo-transistor and photo-darlington devices are mainly employed in direct current (DC) circuits, however the photo-SCR and photo-triac may regulate AC-powered circuits.
A few examples of source-sensor combinations are LED-photodiode, LED-LASER, lamp-photoresistor pairs, reflective and slotted optocouplers.
Individual components can be utilized to make basic opto-couplers at home. An LED and a phototransistor are placed in a hard plastic tube or wrapped in heat-shrinkable tubing, as shown. The advantage of this handmade optocoupler is that the tube may be cut to size.

Reflective tubing is obviously more efficient than dark black tubing.Optocouplers and opto-isolators can be used alone or in conjunction with larger electronic devices such as transistors and triacs to provide the required electrical isolation between a lower voltage control signal, such as one from an Arduino or microcontroller, and a much higher voltage or mains current output signal.
