A Raspberry Pi is connected to a temperature sensor and 2 LED displays to display time and temperature. By connecting Pi Clock to a network, advanced functions may be implemented, such as
1) Displaying the temperature from a remote networked sensor
2) Recording temperature to a database for charting on a web site.
3) Serving as a security camera (with the addition of a camera board module)
