The begining

Hi, some time ago I though it would be a good idea to monitor the temperature of every room at home. I have a very bad HVAC installation because temperature sensors always read almost the same temperature (around 28ÂșC) and the air is too cold or too hot. The brand of the HVAC equipment is very popular but I am not going to say its name, I am pretty upset with both the equipment and the company who made the installation. Anyway that's not the topic of this blog. The idea (just for fun) is to install a network of sensors capable of reading true temperature of every room and transmit them to my main PC. It will be achieve using several 1-wire DS18S20 temperature sensors from Dallas Semiconductor and a microcontroller from Atmel. The progress of my project will be shown here.
