What is a Micro photo sensor?

A microphotosensor is a device that uses light to detect the presence or location of an object. They are generally divided into transmissive photointerrupters and reflective photoreflectors. It is very small and is used as a built-in object for various machines. After emitting light, you can measure the state of the object by investigating how the light returned. Infrared LEDs are generally used as light emitting elements. In addition, it is widely used because it is inexpensive for its performance.

Application of Micro photo sensor

Microphotosensors detect objects using light, and the method that is suitable for each application is different. The first is a transparent photointerrupter. It is a highly reliable device because the object to be measured is sandwiched between the transmit and receive terminals. For example, it is used to detect items that require high accuracy, such as cash and tickets. Next is a reflective photoreflector. This method is suitable for measuring objects at a certain distance due to the structure in which the emitted light is reflected and received by the target object.
