Prepare Your Plumbing for Winter with This DIY Frozen Pipe Alarm

With the deep freeze of winter on its way, now is the time to start preparing your home if you live in a colder climate. Frozen pipes can burst and cause nightmarish amounts of damage, but you can build an alarm that warns you of dangerous pipe-freezing temperatures.

Jason Poel Smith at Make has put together a step-by-step guide for the frozen pipe alarm over at Instructables, and it explains each step to building this anti-freeze setup. You'll need an Arduino Microcontroller, a Thermistor, an LED light, a Piezo Buzzer, and a few other common electronic parts. Some soldering is required, but it's minimal compared to other projects. Once you've calibrated the sensor and placed it near your pipes, you'll get a buzzer sound along with a flashing LED to let you know the temperature is getting dangerously low. For the complete guide, check out the link below.
