SUMMARY
The discussion focuses on amplifying a 0-5V DC output from a humidity sensor to a 0-10V range for an automatic irrigation system using a PLC. The recommended solution is to implement a non-inverting operational amplifier (op-amp) circuit with a gain of 2V/V, utilizing equal resistor values (R1 = R2). This configuration effectively doubles the input voltage, meeting the PLC's requirements for optimal performance.
