Hey, I have a current sensor that output 4mA to 20mA. I plan on using a resistor value of 226ohm which gives me 0.9V to 4.5V. I was planning on measuring the voltage with analog input of the microcontroller but I would like to use a low pass filter before measuring the voltage.
Low pass filter is important as well as low drift. Can you please recommend me one. In addition, would you add anything to this circuitry to make it even better/ safer.
