I have a pressure sensor giving an output between 0 - 10 V.
I want to read and save the value using an arduino, so I am using a voltage divider (https://learn.sparkfun.com/tutorials/voltage-dividers) to scale it down to 0 - 5 V. Since I want to halve the voltage, I am using the same resistance twice.
I have noticed that the voltage changes according to the value of the chosen resistance pair. I assume this is due to the output impedance of the sensor.
On the sensor there is a label reading "OUT 0...10 V RL>10K". I assume this is the impedance of the output.
Does this mean that one should use a pair of at least 10K Ohm resistance for the voltage divider?
