IR distance sensors are generally shortrange solutions that are used individually, as they cannot reliably be compounded with additional sensors. Laser Distance Sensors Proximity sensing with monochromatic laser light typically utilizes a laser source with integrated optics to measure the time taken for a narrow beam of pulsed light to reach an object and reflect to the sensor.
This extralongrange SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. Comes with 6" long 6JST interface wire. These sensors are good for detection between 100cm500cm (15 meters / 315 feet).
