New project for 8 Temp Sensor with logging

Projects General Guidance
1

I need to create a circuit to monitor 8 temperature sensors, and also save the data to be analysed later.
This sensors will be attached to a moving part, so i'll need to place a flat cable with ~ 5m lenght - the picture shows were the part - http://www.etel.ch/typo3temp/pics/DynX_dual_motor_gantry_748d881693.jpg

Can some one help and advise what is needed?
I'm new to arduino so all help is welcome.
I need to know wich parts are needed: arduino board Uno?, LM35 sensors?, communication board or SD card?

Thanks in advance for all the help.

more data is needed or we will speculate you to death.

what temperature ranges? not all sensors are good a 1,000°C
how often do you need to sample/control ?

I see you could have the whole unit on the carriage and send wireless. that way, local control, remote monitoring and fewer wires.

Also, how accurate of measurements do you need ? serial temperature sensors are easier, but not as accurate.

If you use DS18BS20 you can have all the sensors on the same bus, receive the data via DS ONEWIRE protocol and then transmit that as needed from the arduino. At this point I don't know which arduino to recommend.

Many thanks for the replies.
In need i forgot some important details.

Temperature range will be around 20~80 °C and accuracy around 0.5°C is ok.
Samples needed are ~30 seconds for 12 Hours (during setup, i may need a smaller sample #5 seconds).
I would like to add the circuit inside the machine, and store the data somewhere else (SD card or a PC via USB or Wireless).
The final solution is to be able to monitor this data on a 24H/7 days continuous but with samples of 30~120 seconds

Best regards and thanks for all the help
