8051 Timer Calculation Code Timers Of

Counters counts the external clock source whereas the timers counts the clock source from the oscillator used.

Loading logic 0 in the TMOD register will activate the timer mode in 8051 microcontroller.

8051 Timer Calculation Code Timers Of

In this code timers of 8051 have been used as counter so with every switch press value in the timer register will increase by 1 and it will be displayed in the LCD.

You need to program one timer to count time and another to count pulses.

Write your code in such a way the counter counts the pulse for 5 seconds and then multiply it by 12 and you will get your pulse per minute.

When you mean speed sensor what exactly is that, can you give the sensor specs.

In my code counters will count the incoming pulses and display it in the lcd when coming to working with RPM you need to do some calibration before printing the values.

Specify the speed sensor spec i might be able to help you out.

If you are doing project to count peoples then you can use this Peopleobject counter circuit.

Connect the 3rd pin output pin of the TSOP to P3.4T0 of the Microcontroller, thats the sensor part the code remains the same.
