Estimate RPM from signal pulses received from IR sensor connected to Arduino on Simulink

Hi

I need to control the speed of a DC motor with the PID controller that I have designed. I am using Arduino for controlling the motor and an IR sensor to get the speed.

I just wanted to know how I can do this on Simulink to get the speed of motor in rpm because IR sensor output is a train of pulses whenever it is triggered, and I want process these pulses on Simulink and get the speed.

Thank you.

Does it give logical pulse?

yes.. It outputs a logic 0 whenever the sensor is triggered

Do you have the datasheet for your IR sensor?

I could not find the datasheet, but i can give you the link from which resembles the same https://www.aliexpress.com/item/TCRT5000-infrared-reflectance-sensor-Obstacle-avoidance-module-tracing-sensor-tracing-module/32758692268.html
