PID Beginner''s Guide • Renegade Robotics

Jul 22, 2018· PID algorithms are used in combination with sensors: the algorithm checks the value of a given sensor (the “process variable” in PIDspeak) and compares it to a predetermined target (called the “setpoint” in PIDspeak), and changes the motor power based on those sensor readings. It does this process over and over and over in a while loop.

Jan 04, 2016· 2. Humidity is a problem. Humidity is a huge problem with some PIDs. Most PIDs and their users are blind to RH effects: Water vapour scatters and absorbs photons, reducing the PID output. This is also called ‘quenching.’. With high RH, you may find current leakage along the sensor walls, resulting in higher than actual readings.
