Reflective Optical Sensor TCTR5000

How it works
This sensor is reflective with infrared light and it contained emitter and phototransistor in a leaded package. This sensor will send the signal HIGH(1024) when it sees light color or reflection and it will produce down to LOW(0) when it sees darkest. So we can use that range for many different tasks depending on the project.

Circuit:

This sensor has for legs which we have to be careful when we attach it. The image below will help you to see and understand which leg should be working the right way. Please see the image below:
