hi guys

I just bought LM70CIMM-3 which is digital temperature sensor and I want to connect it in arduino USB board

the problem as u can see is the chip is too small and the pins can not fit in my board, further more the wire is too big for it

so any one can help me in this issue

You would use SPI to talk to it. Look at the playground for SPI tutorials. Older boards with the LED on pin 13 can be a problem

yes I know Arduino support SPI but the sensor is too small I could not figure out how to interface it with my board

I barely see it by my eyas

Hi,

You'll want an "adapter" or "breakout" board that converts it to a "normal" breadboard 0.1" pin spacing.

From looking at the product information page (always good to include a link to such a page with your question) I assume you have the "MINI SOIC" package.

You will want a SOIC to DIP adapter board like this one although you'll need to confirm for yourself the exact type of adapter board you require.
