What does a Photointerrupter do?
A Photointerrupter is a transmission-type photosensor, which typically consists of a light emitting elements and light receiving elements aligned facing each other in a single package, that works by detecting light blockage when a target object comes between both elements, acting as an optical switch.
How do I test my Opto sensor?
Testing optical sensors is simply done by using a nonmetallic object and break the signal between the two sensors on the optical sensor PCB (use nonmetallic material in order to avoid shorts if you accidentally touch an electrical component).
How do I connect Arduino to Photointerrupter?

- Step 4: In Visuino: Connect the Analog In 0 to the Serial Port.
How can I test my printer sensor?
Press and hold the Left Arrow and Tick/Select keys on the operator panel. With the keys still held down switch the power back on. Keep holding the keys until the screen displays “Diag Menu”. Press the Right Arrow until “Base Sensor test” is displayed, press Tick/Select.
How do line tracker sensors work?
The line tracking sensor works by detecting reflected light coming from its own infrared LED and by measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it.
Why do we use optical sensors?
The purpose of an optical sensor is to measure a physical quantity of light and, depending on the type of sensor, then translates it into a form that is readable by an integrated measuring device. Optical Sensors are used for contact-less detection, counting or positioning of parts.
