Winter is coming. So it is time to make preparations. If you live in a colder climate, you need to be concerned about the possibility of your pipes freezing. There are a lot of preventative measures that you can take such as insulating your pipes and leaving the water dripping. But for a little extra peace of mind, I designed a simple alarm that will notify me if the pipes are getting too cold and are in danger of freezing.

Step 1: Watch the Video

Here is a video walkthrough of the project.

<p>Now this I can use. Great idea.</p>
<p>Can somebody please explain in more details(preferably with photos), on how to set up the final printed circuit board. I understand that there arent too many parts to it but it is hard to see what goes where and I really want to build this. </p>
<p>Not sure if you already found out how to do it, but in case you didnt, it is really well described in the ibble (nope sorry, I dont have pictures, didnt even build it), and it is also very clear in the code.<br>Take your fixed resistor and connect it between ground and A0. Those pins are clearly indicated on yr arduino.<br>Take your NTC and connect it between +5Volt and that same A0<br>That is your sensor input<br>Your alarm pin is digital pin 9. He uses both an LED and a piezo buzzer. <br>You have to make sure the current does not exceed 40mA.<br>Suppose you would only use an LED then get a resistor of 1kohm and attach one end to D9 on yr Arduino and connect the other end to the anode of your LED (usually the anode is the long leg). Connect the kathode (usually the short leg) to Ground and you are set.<br><br>if you want to add a buzzer this ibble puts that parallel to the LED, but you may have to take a lower value for the resistor. but make sure you do not draw more than 40mA<br></p>
<p>Great Project....</p><p>How about sell it with heat cable with connect relay.</p><p>I think there are many who need it.</p>

Great build. My family has been using a thermostatic controlled outlet in the well house (very small insulated shed) for a few decades. It automatically turns on a 100w light bulb to raise the temp enough to keep the water flowing.<br><br> http://www.amazon.com/Farm-Innovators-TC-3-Thermostatically-Controlled/dp/B0006U2HD2
<p>I LOVE THIS PROJECT. It's an excellent entry in the Winterize contest, and it was pretty much exactly what I was looking for when I launched that competition. </p><p>Nice work. </p>
<p>That's so clever, and very necessary is some parts of the world! Looks like it works great and the instructable is easy to understand!</p>
