Temperature measurement using panstamp

Question

Hello guys, I'm new in this field and I want to ask you what is the material that I can to add to panstamp to measure the ambient temperature . Thanks in advance

I didn't know what a Panstamp was, but it looks like its a radio-equipped Arduino-like board. Nice looking board.

One way to read ambient temperature with it would be to use a part like this:

http://uk.farnell.com/microchip/mcp9700a-e-to/thermistor-linear-0-01v-c-to-92/dp/1332164

It operates from a supply of anywhere between 2.3V and 5.5V, and only takes 6uA so should be fine for battery operation. The output is designed to drive an A/D input well. Use a decoupling capacitor between the Vdd pin and GND close to the device. [The Vdd pin is the positive supply.] A 100nF ceramic capacitor should do. If the readings you get jump around too much, try upping the decoupling capacitor value.

If you want really, really low power operation, the datasheet points out that you could get the power from a processor output pin so that the processor can power the device only when it's needed.

You will need to do some calculations with the values you get from the analog input to translate them to either Centigrade or Fahrenheit. If you're not sure how to do that, come back and ask; I'm sure someone will help - there are plenty of people here with Arduino coding experience.
