OSOYOO 10PCS IR Infrared Obstacle Avoidance Sensor Module for Arduino Smart Car Robot Raspberry PI 3. These items are shipped from and sold by different sellers. I am using one because I have one handy and it help debugging , if you plan on doing something a little more complex,in the field. The best part about the Adafruit Feather HUZZAH in addition to its WiFi capability, is that you can use a Lipo battery and it has a built in battery charging circuit, which means you can use the sensor node when you are out an about.In the picture above, I am using a OLED feather wing, which is not really required.

The receiver is open collector transistor output which means that you do need a pull up resistor if you want to read a digital signal off the signal wire. element14 is the first online community specifically for engineers. One reader asked how to use my Arduino Infrared Library to detect breakage of an IR beam. Get going quickly with these simple IR breakbeam sensors, "Another belief of mine; that everyone else my age is an adult, whereas I am merely in disguise". The transmitter is on the right, it has two wires. Compared to PIR sensors, break beams are faster and allow better control of where you want to detect the motion.
