This two temperature sensor Arduino Ethernet web server uses an Arduino, Ethernet shield and two MCP9700 temperature sensors to measure two temperatures.
The temperatures are displayed on two gauges on the web page hosted by the Arduino web server. The two sensors can be used to measure an inside temperature (e.g. inside a building or room) and an outside temperature (e.g. outside air temperature).
Tutorial 15: The Arduino reads temperature from a MCP9700 temperature sensor IC and displays the temperature in the Arduino IDE serial monitor window.

In this tutorial, a temperature sensor (MCP9700 linear active thermistor IC) and LCD are connected to the Arduino. The Arduino reads the temperature from the MCP9700 on analog pin A0 and displays the temperature on the LCD.
