I am new to Arduino and I am trying to use it to collect data from my Keyence IR Temp sensor for research purposes.
The Keyence IR Temp sensor has an Analog Output cable (Pink) which output a current that is ranged from 4mA - 20mA based on the temperature it sense.
I know the Arduino takes voltage as analog input, so I need to find a way to convert the current output signal from the Keyence to voltage. So, I just wanted to make sure if my wiring is correct (See Figure 1)
Here I used a 220 Ohm resistor to do the conversion, but I am curious if it works or not.
Please correct me if I am wrong, thanks!
