VMA421 for watering system, dry run?


I’m planning to make a watering system for my tomato plants. I have a water tank and need a pump to pump the water to the plants.
Is VMA421 a good choice?

Some more questions about VMA421

  • can it run dry without damage? Or does it have dry run protection?
  • is it possible to control the pump speed using an Arduino? Do I need some extra electronics?
