malfunction the device after few days ..

Post by chatura » Sun Jul 19, 2009 6:33 am

Dear Friends ,

I designed and fabricated a humidity based fan controller , for use in a factory. It worked fine , when It is in my home. But after installation the device in the tea factory , after some days , the unit is showing strage behaviors. It is not do the correct humidity calculations , after some days. So then
I have to power off and on again.

I checked again my code , I was unable to find any wrong on that. Is anybody have any idea about this ?

Thanks

Hi Friend ,

In a enviroment like , tea factory , there are lots of elecromagnetic interfearances could occure , bacause of high power Motors.
So this could badly effect to microcontrollers RAM and could lead to change the data in the RAM. So if your program have initializing routines ,
which set some register settings , it is best practise to initialize them again and again after pre determined time interval.

So if the register settings corrupted , They will re initialize to correct values , after some time.

Good Luck !
