The Grove – I 2 C High Accuracy Temperature Sensor (MCP9808) is a pretty cute module based on MCP9808. In addition to high-precision temperature measurements, the module also offers a programmable ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

The Arduino slowly scans the sensor in a grid, taking readings along the way. A Processing application then takes each reading and compiles the final image.
