Hi,
I'm new here and to electronics in general. I've built a Tig welding cooler that takes water from a built in container, pumps it into a Tig torch and then back into a fan cooled radiator and back to the container for recycling. I've added a water flow sensor (ebay:New 1/2'' Water Flow Sensor Control Effect Flowmeter Hall 1-30L/min For Arduino) to the output of the pump. There is a built in power supply for 120vac and 12vDC. I need help with the electronics side of things to finish the project. How do I convert the pulse side of the flow sensor (3 wire) into DC voltage, take readings so that I can have a trigger for low flow to a 12V LED and 12V buzzer? I'd like to be able to adjust the low trigger via some kind of variable resistor.
Thanks in advance for your assistance.
