Hi everyone,

New to the forums and new to circuits and electronics, so forgive the dumb questions, trying to learn.

I want to create a skin temperature sensor to measure slight changes in skin temperature variation with an Arduino Uno.

I was looking at the TI TMP006 (http://www.ti.com/product/tmp006) sensor but not quite sure what IC I need or the best way to integrate the IC with a bandage or strap, for example, to display the temperature data in the Arduino console.

Would love to hear some thoughts and help on what I need to buy, learn and assemble to get this made.

Thanks in advance

 

Since the sensor communicates through a serial line, you will need a microprocessor to read the temperature. The microprocessor can then display the temperature on an LCD.

 

Right, I get that. The arduino would be the micro controller in this case and the output would be in the arduino console. My questions were: what is the right sensor for skin temperature with a high-degree of accuracy and variability and what are some additional components I would need? I.e. ADC, etc?

 

I'd use an LM35 and one of those free multimeters you can get. The output voltage of the LM35 is 10mV per °C, so body temp will read 0.370 volts. Total cost less than $1.

 

I'm cheap, so a bead thermistor & a DVM , with a low V battery would have to do. A μC could take out the non linearity & display results.

 

Thanks for the tips guys. I was able to get a bunch of free samples from TI, so I'll be using those. I guess from a beginners perspective (me) - any recommend tutorials or reads on how to build a skin temp sensor with an Arduino?

 

What are you really trying to do? Skin temperature is hard to measure accurately without the measurement itself changing the result. In fact I think you'd need a non-contact technique (like IR) to get an accurate value. Any belt, pad, bandage, etc. will influence the result. That may be OK if you're looking for changes.
