IR Infrared Obstacle Avoidance Sensor Module can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on.
the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted
The output port OUT sensor module can be directly connected to the microcontroller IO port, you can directly drive a 5V relay.
It has a pair of infrared transmitting and receiving tube, tube infrared emit a certain frequency, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving tube, after the comparator circuit processing, green indicator will light up, at the same time signal output interface to output digital signal (a low level signal).
Can be used for 3-5V DC power supply modules. It has red power indicator.

FAQ
Q: Will these work with a Raspberry pi?
A: Yes, they should as long as you have the proper pin input/output connections.
Q: Could you use these for a line following robot?
A: Yes you can program these IR sensors to follow a black or white line.
Q:Is this sensor works for 3d printer?
A: No
The resolution is not good enough for fine edge sensing. I am using this for starting and stopping a dice game with the wave of a hand.
