I am making a high range and fast Obstacle detection system , HC-04 is slow for that, other sensor don't have the range and Lidar is too costly.

Any idea how to make a long range(more than 10m) high speed Obstacle detection system

  • adafruit.com/products/3316 isn't the range, but is probably a lot faster. I don't think there is a solution that fits all your requirements.
