Distance Infrared Laser Sensor 50m/80m (DFRobot)

AED 449.50

Low stock


The IR laser distance sensor is a cost-effective solution offering high accuracy, long-distance detection, a visible IR laser, and a small field of view (FOV). It provides measuring ranges of 0.0580m indoors and 0.0550m outdoors, making it versatile for various applications such as UAV automatic landing, electronic scale, and barn material level monitoring. With serial port output, it's compatible with controller boards like Arduino. Its visible infrared laser and small FOV facilitate precise measurements even on small objects within the specified range.



  • High Accuracy: Ensures precise measurements with a standard deviation of ±1.0mm.

How does it work:
Visible Infrared Laser, Small FOV :The sensor will emit infrared laser to point to an object, then there will be an IR laser dot on that object. It can measure objects of size 5x5cm within 80m when used indoors. Long-distance detection of small objects, more accurate and easier to use.High Accuracy, Long DistanceMeasuring Range 80m for using indoor, 50m outdoor. 0.05m Blind zone  


Package Includes:
