Opto Reflective Sensor Project

They are a non contact type of sensor often used in the automation industry.

Opto reflective sensor project.

These days opto reflective sensor is used in various project like proximity sensing position detector robotics etc. Its range is 2mm to 10mm and the best response range is 5mm. Thus we had posted a diy project with working range of 2mm to 10mm.

Here a beam of infrared light is emitted at an angle by the led and if some reflective material is placed about 3 to 4mm from the sensor the light beam from the led is reflected back onto the phototransistor causing it to conduct and produce an output current. It can be used to sense objects in close proximity or even detect the difference between black and white surfaces.

A polarized retro reflective photoelectric sensor must be used with a corner cube reflector which is a type of reflector with the ability to accurately return the light energy on a parallel axis back to the receiver. The module used here is tcrt5000 which have an infrared led and a photo transistor fabricated internally.

Photodetectors like these are critical components for projects ranging from line following robots to close proximity detection in smartphones. The circuit uses an optoreflective sensor module that has an infrared ir led and a phototransistor in a common package. 5 4 1 b the infrared led and the phototransistor are mounted side by side in the narrow end of the switch. Reflective optical sensors are photoelectrical sensors that are used to detect the presence or absence of objects or measure the distance to those objects.

Optical sensor based liquid level indicator consist of two main parts an infrared led coupled with a light transistor and a transparent prism tip in the front. Polarized retro reflective sensors are recommended for any application with reflective targets. The led projects an infrared light outward when the sensor tip is surrounded by air the light reacts by bouncing back with in the tip before returning to the transistor. They can be used to provide real time information in a manufacturing setting in order to keep processes running smoothly.
