Infrared Proximity Sensor
This is an Infrared Proximity Sensor – great for adding obstacle avoidance functionality to your Arduino robot project!
The sensor emits a beam of light and receives the reflected beam back, which is then used to calculate distance from a nearby object. The sensitivity can be adjusted using the onboard potentiometer.
A 4-pin XH2.54 wire is included, which has female jumper ends for connecting to your microcontroller.
