Good Morning,
I have a 12 volt trolling motor on my boat that uses wireless technology to change speed, The only indicator is a small "beep" when speed is increased or decreased. My hearing is so poor that I cannot hear the "beeps" and don't have a clue if the motor is running fast or slow or even if it is on or off. I need a visual indicator to give me this information. The current draw on the motor is about 7 amps on low speed up to 30 amps at the top speed. Since the current draw is relative to speed, I would like to find a circuit using a Hall effect current sensor to drive a digital microamp meter. The meter would serve as a speed indicator and an "off-on" indicator as well. Can someone point me to a circuit I could adapt to fit this criteria? I have never used a Hall sensor before. Thanks.
