35 pcs LM35DZ and arduino uno board, how to?


Im looking for a solution on this problem. I would like to have 35 LM35DZ sensors for a project of mine.. But i only have my arduino uno board.

What to do? I could imagin that a multiplexer would do some of the work? But know nothing about multiplexer nor the diagram setup...

Any help?

Thanks. Regards from: Danni Hansen - Denmark.

Hi Danni,

Check these multiplexers - http://www.sparkfun.com/products/9056 -

and read this blog - http://bildr.org/2011/02/cd74hc4067-arduino/

might get you a step further.

I don't know how easy you can order these multiplexers in Denmark.

Hello and thanks for reply'in.

I might be abel to get them in Denmark, but we have some strange taxes, so i would like to build it from scratch if you understand?

Found this: http://viewitem.eim.ebay.dk/CD74HC4067E-CMOS-Logic-16Ch-MUXDEMUX-74HC4067/300559049062/item

Now i just need to know how to build the rest... :)
