Motor Speed Tester Using Arduino & IR Sensor : 6 Steps ...

Advantage of using IR sensor for maintaining conatsnt speed of DC motor. Suppose somehow load is increased on the motor. Which will reduce the RPM of motor. By checking real time rpm, arduino will sense that rpm has been reduced. Accordingly arduino will send signal to increase power supplied to the motor in order to compensate the reduced RPM.

arduino - Wheel encoder using an IR sensor - Electrical ...

I made a rotary encoder using a IR sensor and a wheel with printed black and white spokes. Everything seems to work but I'm wondering if there is a better way to code this. The IR signal looks ideally like a square wave and I have it looking for the rising edge of each wave. Then calculate the time between rising edges to calculate the wheel's RPM.

Arduino based RPM counter with a new and faster algorithm ...

Apr 30, 2020· This project is developed from scratch as an attempt to measure the exact RPM (Rotations per Minute)value of various motors using a single IR sensor, an Arduino board and an essential key ingredient -a Laser Pointer(necessarily Red).. This project uses the fact that the IR sensor also reads the the low number of IR radiations given off by the red laser.

How to make Arduino Tachometer - Electronic Smith

Nov 20, 2020· RPM Sensor. The formation of the sensor is based on IR phototransistor or IR LED. This transistor is responsive to the infra-red waves only and hence avoid other light interruptions happening in the environment. The alignment of phototransistor and the IR diode is side by side and R2 resistor transmits the current though IR diode.
