Weather station programme.

[English]

Hi - I have registered to ask help with this programme. I would like to add a pressure sensor to the programme but dont know how to go about it. If anyone understands this please get back to me and Ill go into more datail.

Heres what Ive got. This is for wind direction,speed,temprature wet and dry, relative humidity, solar radiation. Some of the parameters are not in use.

TIA Gordon.

How do you receive data from sensors..using MSCOMM32 via microcontroller?

The data is via data taker. Since posting I have found their forum and recieved a promising reply - thanks for your interest.
