Hello,
I have a requirement to integrate an 8,000-20,000 RPM monitoring device with an Arduino. It is an 110VAC 1/4 hp electric motor that runs at an average of 2,000 RPM'S and is turning a multiplier pulley combination for which I must be able to monitor the RPM's in the driven pulley. I mention the motor specs to give an idea of the size of the application.
So I basically need to install and program a sensor on that second (driven pulley) to be able to monitor the effective RPM's. I have seen solutions where they use an infrared led sensor combination for the case of a propeller where the light signal gets interrupted, but in this case my pulley is solid, so one possibility would be going with a magnet on the pulley and detecting the magnetic pulses going around? Has anybody done this and if so what would your sensor option be in order to interface it with the Arduino?
Thank you much in advance.
