When working in extreme temperatures it is important to monitor your body temperature. In freezing weather, your fingers and toes get numb and you can develop frostbite without even noticing it. Likewise, if your core body temperature can drop too low and you can start to start to suffer the effects of hypothermia before you are aware of it.

So I designed an automatic temperature sensor that will monitor the temperature of your fingers, your toes, your torso as well as the outside temperature. This can help you to stay safe when working in extreme cold.

Step 1: Watch the Video

Here is a video walkthrough of the project.

<p>what is the use of the outside temp sensor? you said you didnt cycle through it so are you getting any feedback off of it?</p>
<p>The outside temperature sensor is mostly for reference. I didn't include it in the initial tests because I was trying to keep things simple for troubleshooting. But it is easy to add. Knowing the outside temperature, will tell you when you need to start worrying about your body temperature.</p>
<p>indeed I see. but as you only have one signal element, I guess you'd need to give that one a different tone or something</p>
<p>Thanks for posting this! I plan to use the same temperature sensors on my sailboat, to measure air and water temperatures for my logbook entries.</p>
<p>excellent idea combined with temperature reactive fabric and it would be awesome</p>
