Hello, I have a project of instantaneous mass flow rate and a chamber which have 3 sensors within it. 2 pressure sensors and 1 thermocouple. I want to collect data from sensors using Arduino UNO. Pressure sensors have 0-10V or 4-20mA output signals. Can I connect them to Arduino or what is required to drop from 10V to 5V, which for arduino is required?
To convert 0-10 V to 0-5 V use a voltage divider. Two 10K resistors will be fine.
To convert 4-20 mA to 1-5 V, use a 250 Ohm resistor in the sensor ground lead.
Thank you! i will check them out
