Hi Glen,

I am using a simple device to measure it. A copper rod suspended horizontally with the help of a fine thread and moving
above a dial marked 0-360 degrees. Every day I am noting its reading subsequently measuirng local humidity and temperature.
Normally the reading would not much affected by temperature but it affected by humidity. Though there was no change in
humidity for the last two days, but deviation in the reading is so high. Hence my post.

Knowing little bit Physics, and with the basis of experience I made the post. If you have comments, please let me know.
