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't detected. Likewise, if something isn't in the way of the sensor, it won'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. 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.

5mm away - 2mm to 10mm worked fairly well but your results may vary with the LED brightness, object shininess, etc.
