I have temperature and light sensors about 3-6 meters from the ADC/microcontroller connected by long wires. The sensor produces analog output. LM35 temperature sensor has output of 10mV/degC. It has 3 pins: Vin, GND, Vout.
I'm quite worried about the quality and accuracy of the output signal of the sensor as it reaches the ADC/microcontroller.
Thanks...

- Is it okay to have 3-6meter wire for the sensor's output, supply voltage and ground?
- Should i add circuits or filter for output and voltage supply?
- Would it be practical/better if i place a voltage regulator on the same pcb as with each of the remote sensors or is it okay to have a long wire from the voltage regulator to the remote sensors?
Thanks...
