My p8055

Introduction

I have a velleman P8055 (usb) (and a serial one as well but usb is easier for now to work with). I want to attach temperature sensors to it and collect some data. I went to the electronic store on college east of spadina and the guy there said that I should use an LM35. Thing is I said: I want a temperature sensor and he shows me an LM35 which has three pins

what is a P8055?

for those of you who buy the kit, and those of you who bought it whole ( as I did) and want to know what it's made of.

Linux

So I have an old t22, which is perfect for this. Had an old gentoo , update profile, emerge -uDp world go to work, come bacK : thooper!

then followed these instruction: http://libk8055.sourceforge.net/#program

worked a treat:

ll src # k8055 -p:0 -num:8 -delay:1000

Talked to my EE friend, maybe he can help me. Stay tuned.

AMAGAD!

could it be any easier?

what about?
a DS18S20 sensor? 1-wire? cheaper? interface?
