Hi guys, quick question for the experts.
I'm playing with a system of thermistors feeding an RS485 Networked ADC to my computor.
My supply is 5V with a 47k resistor as a Voltage divider with the thermistor acting as the low side.
Q: Can i use the same resistor to feed multiple channels or is it better to use a seperate one for each channel?. I'm only useing std cheap resistors but they vary ie 46.1k and 46.3k for
47k resistors. If i feed off the same one I can use the same values in my temperature calculation rather than having to measure each one.Any thoughts please. TIA
