Raspberry Pi CPU temperature visualization

In this article we are going to explain how to constantly read CPU temperature of your Raspberry Pi and send the readings to a web page. The communication between server and client web page is accomplished by using websocket protocol. We used Tornado, an asynchronous webserver for python to make websocket connections. To visualize the readings we [...]
