SKU: SEN-078 Mfg Part Number: 2349 Categories: , Tags: , , , ,


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. If there is nothing in the way it will not trigger so it can be used for basic occupancy sensing provided the detected item is a lighter color.

This sensor also ships with 2 resistors; a 470 ohm for use with the IR LED and a 10K ohm for use as a pull-up resistor on the phototransistor.
