Ethernet Thermometer

One friend told me, he want a digital thermometer for his rack to monitor temperature failure and send email or SMS to him. So I went to shop and order somer arduino, temperature sensor and ethernet interface and a little nice box for all that.

All Data are store in time inverval on my server for later graphs. I dont have them yet because have no time. I made this in one weekend (2 days) as relax 🙂


This is my first Arduino project and therefore I would kindly ask you to be indulgent.

1. Model of Thermometer



2. This is simple GUI for mobile


3. My flat with sensor in my working room for testing





Update 10.10.2014

I’ve ordered wifi module for next wifi version of this.
