I’m searching a proper obstacle avoidance solution for an agricultural drone prototype. Drone’s task is to fly at low altitude between rows of fruit trees and for such task I need a LIDAR capable to detect small objects like branches, fence poles, pipelines\hoses (at least 1 inch in diameter) etc. I need your help in clarification of following:

- Which Field-of-View(FoV): [https://www.sparkfun.com/products/14599](https://www.sparkfun.com/products/14599) this LIDAR has?
  
- Which diameter of a laser spot this LIDAR has: [https://www.sparkfun.com/products/14599](https://www.sparkfun.com/products/14599) has?
  
- Does SparkFun supplies any LIDAR\Sonar solution with:

```auto
        - FoV: 25(or more) degrees + range 30(or more) feet?[/list]
        - LIDAR\Sonar solution with known beam spot diameter at given distance? For example Model-A: has approx. 2 inches spot at 30 feet, 4 inches at 60 feet etc.

```

- Are there any LIDAR\Sonar solutions with standard FoV (1-6 degrees) but larger emitter which due to a emitter size produces larger laser\sonic spot?

If SparkFun supplies any solutions which I didn’t mention, please kindly advise.

Best regards, Sergio.

You might want to look at ToF arrays, like [https://www.sparkfun.com/products/18642](https://www.sparkfun.com/products/18642) or cameras running a small detection algorithm to augment the height lidar

For the other specs browse through our distance category here [https://www.sparkfun.com/categories/84](https://www.sparkfun.com/categories/84) and click ‘documents’ tab to see specific info
