Beginner here. Kind of in a new, slightly intimidating unknown territory.
I need to connect a transmitter which outputs a 4-20mA signal to a Raspberry Pi 4. I’m using an ADC0804 since the Pi cannot read analog inputs. The transmitter has two modes. Here is the 4-20mA mode: https://postimg.cc/mh1MJf7k. It can also be operated with a voltage 40-200 mV output: https://postimg.cc/4Ys9YYqH. How do I go about wiring the sensor to the ADC and then the Pi? Also, what would the code look like to read this value?
Which of these two modes would be easier/simpler?
Thank you very much.
