You really have a point here.

 From 2 days, the temperature has been increasing everyday over here.

I will incorporate a temperature sensor and then take the readings, plot=20
it and come to a conclusion.

I will try out all the suggestions given to me via PIClist and then I=20
will post my results in a week or 2.

Cheers

Ravi
