Hello...
I am working on one project of water pressure measurement, in which i used pressure transducer which gives me output between 4-20mA Current form.
I am using one 250 ohm resistance to convert current into voltage, and than i give this voltage to ADC of arduino UNO channel 0 (A0).
ADC reading is continuously fluctuating up to 10 decimal numbers.
I have also check by connecting multi-meter and measure sensor current reading, for particular pressure. but current reading is stable...
