Hardware Pixhawk family
1

Hello,
I am very new to flight controller & Quad copter.
I am planning to build Agricultural Spraying Drone.

I can successfully build drone using Pixhawk 2.4.8
Now I would like to integrate water pump which can be controlled thru mission planner.

Question-

  1. How to control water pump *( On/ Off / Speed)?
  2. Do i need additional board to communicate between pump & Pixhawk? (Like H Bridge?)

Hardware used-

  1. Pixhawk Fc
  2. 4 in 1 ESC
  3. 4 Dc Motor
  4. Suitable Battery
  5. Custom made Frame
  6. Gps module
  7. FrySky X8r
  8. Taranis Q X7

Dc Pump

  1. 12v Dc Pump
  2. Sprinkler / Water Tank / Pipe etc…

Request your valuable feedback on the same.

Thanks
Rushikesh
