## Description

This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. White & light colored stuff will bounce the light, so you can detect it. Black & dark colored stuff will absorb the IR light so that it isn&apos;t detected. Likewise, if something isn&apos;t in the way of the sensor, it won&apos;t trigger either. These sensors are handy when you want to detect if something has passed by the sensor, or a very simple hand-detector. Also sometimes these are used as rotary encoder, if the encoder wheel has black and white stripes, the photo sensor is fast enough to tell you the RPM. Comes with a 470 ohm resistor (for biasing the IR LED) and a 10K resistor which you can use as a pull-up resistor for the phototransistor. The sensor is breadboard friendly and easy to solder to. This works best when detecting a light-colored object approximately 5mm away - 2mm to 10mm worked fairly well but your results may vary with the LED brightness, object shininess, etc.
