Determine speed from hall sensor output

Hello,
I am working on a student project and want to calculate the RPM of the wheels and thus the speed of the vehicle using a hall sensor. Assuming the hall sensor output can be simulated as a block signal with a varying pulse interval as the speed changes, how can I determine the time t(n)-t(n-1) where n indicates the occurence where the output signal rises above a threshold value for a continous signal? In other words: I want simulink to scan a continous input signal and output the time difference between the two most recent peaks.
Any help is appreciated. Thanks.

please i have a similar problem i need help too. am using brushless dc motor with 3 hall effect sensor. i need to get speed from the hall sensor so as to feedback in a simulnk arduino. i am implementing fuzzy PID on arduino uno board. please i need help urgent in orther to help me complete my thesis. am a master student in control and intrumentation. thanks.

Please I am having the same problem. I want matlab code for calculating the speed and position of the motor using the signals of the hall sensors.Thanks.

Hi Robin,
Please go through the model that I have attached ' DifferenceofPeaks.mdl' and see if this works for you. An explanation of the model is also provided.

Sir, can you send me the matlab code for calculating the speed and position of the motor using the three signals of the hall sensors.
