Good day everyone,
I have a design project to complete that requires my group and I to build a speed control of an induction motor. My responsibility is the speed measurement unit which requires me to track the speed of the fan in rpms and display the speed and temperature on a multiplexed seven segment display. I have found some research that uses IR leds and a phototransistor but i am having trouble finding a suitable implementation and circuit diagram.
Any help would be greatly appreciated.
Thank you.
