View source for Infrared Range Sensors

Infrared range sensors are used to measure distance from the sensor. They provide a value that has a non-linear relationship with distance.

They are based on infrared, so they may have problems with high luminosity in the environment and in sunlight.

They are now considered better than sonar in most situations.

They have different ranges.
