About this product
A reflective photoelectric sensor with an LED emitter (visible or infrared) and a phototransistor receiver. It detects light reflected from a nearby target, and can also work in through-beam mode where a target breaks the light path. Typical uses include edge detection, disc or timing sensing and liquid level sensing.

How do I read the output?
Connect the phototransistor collector to the supply through a pull-up resistor and the emitter to GND. Read the collector node with a digital input. The voltage goes low when the phototransistor receives enough light.
Does the LED need a series resistor?
Yes. Place a current-limiting resistor in series with the LED anode. Its value depends on the supply voltage and the LED's forward voltage and current rating, so check the datasheet of your specific part.
