Useful project from Make shows how to set up wearable temperature sensors for working in the extreme cold.

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 drops too low, 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, and your torso, as well as the outside temperature. This can help you to stay safe when working in extreme cold.

TMP36 – Analog Temperature sensor – TMP36: Wide range, low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature. To use, connect pin 1 (left) to power (between 2.7 and 5.5V), pin 3 (right) to ground, and pin 2 to analog in on your microcontroller. The voltage out is 0V at -50°C and 1.75V at 125°C. You can easily calculate the temperature from the voltage in millivolts: Temp °C = 100*(reading in V) – 50 Read more.
