PC based Data aquasition, temp, airflow

[gizard]

Anyone know of a PC based kit for measuring Temperature and airflow. I need to measure air temp and flow in at least two places at the same time. - I don't want to spend a huge amount of money though.... any ideas? I had a look at maplins and only came up with TMD90 and TMA10 which are sort of what I want but a little pricy...
