DIY ethernet temperature and humidity logger

DIY-Ethernet-Temperature-and-Humidity-Logger

Kerry Wong built an Ethernet temperature and humidity logger:

I used an ENC28J60 Ethernet module along with an ATmega328p microcontroller to log the temperature and humidity readings and then process the data on my web server for display.

To plot the data points, I used Google Annotated Timeline so that you can easily zoom into the desired date/time range.
