Frozen Pipe Alarm Using Arduino

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.
