I want to monitor the temperatur around the house and outside. I want to save the data to mysql and then create some kind of webapplication that displlays the data. It is pretty easy to find temperature sensors that transmitts over 433Mhz, and I have thought about Telldus tellstick to receive data and store them. This receiver costs about 30 - 40 $ and 10 - 20 $ for each sensor.
But since I just learned that Arduino can be used for everything, I would love to hear more about it.
Can someone please give me an introduction to what I would need to make this solution? The arduino should basicly receive data from 433 Mhz sensors and store it to MySQL.
What woulds be the challanges when doing something like this?
