You can control the IR LED and turn it on to transmit IR light across the gap, to the detector on the other side. This makes it perfect for detecting when something is in the slot. When there's something blocking the light, the sensor turns off, when the object goes away, the sensor receives the IR light and turns on.\u003c\/p\u003e\u003cp\u003eThese sensors are handy when you want to detect if something has passed through the sensor slot, we think it's great when paired with our slotted encoder wheels - as you can see we have a demo that will count the number of transitions (slots) over a second, extrapolate that to RPM, and display on an OLED. This sensor is extra fancy with a red LED on the side to let you know when the sensor is triggered, and built in protection circuitry.\u003c\/p\u003e\u003cp\u003eWe will mention the one down-side to this sensor is that the circuitry inside has power requirements - the Vin line must be powered by at least 5V. But, the output transistor is open-collector so you can connect a pullup resistor to 3V for 3.3v logic if you need. So, as long as you have some 5V power output, you can use it with a 3V device like the Feather shown in the demo.\u003c\/p\u003e\u003cp\u003eThis version is very fancy with a cable attached:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrown wire - \u003cstrong\u003eVCC\u003c\/strong\u003e (logic circuit power 5-24V)\u003c\/li\u003e\n\u003cli\u003ePink wire - \u003cstrong\u003eL\u003c\/strong\u003e (LED configuration, see datasheet for options but we just tie to VCC)\u003c\/li\u003e\n\u003cli\u003eBlack wire - transistor\u003cstrong\u003e output\u003c\/strong\u003e.
