Last summer I developed automatic watering system for my garden. I use mini submersible 12v water pumps and soil humidity sensors. All worked fine and the only issue was when water level in a tank drops below the leverage of pump, the pump breaks.
Can you please recommend some good, reliable, submersible water pump with overheat protection, e.g that can be run dry?
Of course, there is also the solution with some kind of water level sensor, but it cannot be submersed in water. If there is some water level with plastic box that can be submersed into water, that recommendation is also welcome, so I can implement switching of the pump as soon as it goes out of water. But here I also see some possible limits and constraints, so the pump with overheat protection would be much better in my opinion.
Thanks in advance,
