Sensor for ardupilot 3.6.9

which sensor best for landing and terrain follow on ardupilot 3.6.9 .

Good day, pls update your firmware to the last stable version…, as landing sensor or terrain following you can look for the teraranger evo 60 i2c or the tf mini lidar plus uart/i2c…in case you can make it work also on a CAN BUS node

hello David,
if I am using updated version in that case battery percentage issue bcz we don’t have smart battery if i am using normal lipo battery in that issue is this if plugged battery every time his assume 100% percentage if you have any solution for that how to set that’s good for me.

There is no solution for that. Battery voltage is not a useful measurement of capacity.
