This project consists of two temperatures that are measured by the Arduino using two MCP9700 temperature sensors.
An Arduino Uno and Ethernet shield are set up as a web server that hosts a web page to display the two temperatures on two gauges. The web page is stored on a SD card that is plugged into the micro SD card socket on the Ethernet shield. A web browser is used to display the two temperature gauges on any computer connected to the same network as the Arduino.
The video below shows the project working with the two MCP9700 temperature sensors connected to the Arduino using a breadboard.
