Rangefinders (landing page)ΒΆ

Copter/Plane/Rover support a number of different rangefinders including Maxbotix Sonar and Pulsed Light LED range finders. Rangefinders are used to provide precise altitude information when close to the ground and/or provide proximity sensing for object avoidance.


RNGFND_MAX_CM must be set to a tested, appropriate value. If RNGFND_MAX_CM is set to a value greater than the range of the sensor, the flight controller will not respond correctly to the data provided.
