And now a project for those in much cooler climes than Melbourne - a frozen pipe alarm by Jason Poel Smith. This is quite a simple yet effective project, which uses a thermistor as a temperature sensor. This component changes resistance based on the temperature, so the change can be measured by an analogue input on the Arduino.
Once the analogue reading for almost-ice water is determined, the Arduino can alert the home owner through an almost infinite number of methods to get your attention. A quick run through of the project is shown in the following video:

If you're interested in measuring more ambient temperature levels, consider using our TEMP: DS18B20-based temperature sensor module:
which uses the Dallas DS18B20 1-wire digital temperature sensor, with a wide measurement range of -55 to +125°C at an accuracy of +/- 0.5°C. For more information, tutorials and to order - visit the TEMP: page.
