Hi I m new to arduino but good at coding. Have a good understanding of atmel 8051. Will be coding arduino after some decade.
I want to control a 2 horsepower deep well water submersible pump. I want the controller to start the pump for 10 minutes after every 3 hours during night time say from 9pm to 6am.
So I need a ds3231, a relay board.
I need to know the rating of the relay the full load amps of motor is 9amps.
Second question the bore is 300 feet deep and will be pumping water to overhead tank at second floor. At times there is no water on borewel so running motor dry will damage it. What what are my options to make sure that the motor runs only when water is being pumped out.
