Data Logger to store the hours of running

[ncarthic]

I am using PIC12F1822 for my project to run a AC induction motor. It switched on every time when there is a signal from the Hall effect IC which acts as a flow sensor. I want to monitor the time every time when the motor gets kicked Off and save the dat in the internal memory. I dont know how to start. Can anyone help me here please? and it is very urgent , please....

PIC12F1822 have 256bytes EEPROM size, to store more data you need external EEPROM IC. You can use I2C/SPI protocol for this.

One question you need real time to say when motor is off like 13:40:07-14:02:34 ? In that case you need to use RTC IC.

How long you need to log this few hours, one day, week, month, ... ? You need to determine needed size of EEPROM.

This uC have 128bytes of RAM, your code should be optimized.



Best regards,

Hello Peter,
Thanks for your reply. I appreciate it. I am using a PIC12F1822 to control my motor operation. when ever there is a input from the flow switch to the PIC then it switch on the motor via an Opto-Isolator. I actually want my PIC12F1822 to store the total time in its EEPROM whenever the motor runs. So when I want to see how long it ran for then I can do so by reading the EEPROM. Please see attached the diagram which shows how I want it. I want to allocate 4 bytes from the EEPROM. One for seconds, one for Minutes, one for hours and one for Days. Can I do by timers? I am new to the C program and so I dont know how to start it? or what is the concept that I should follow? I know one of the person did this in his project but I cant ask him. I want to know how to program for this. If anyone can help me, that will be really helpful.

Thank you.
