THE EFFECTS OF PID PARAMETERS ON TEMPERATURE CONTROL OF UNINSULATED ENVIRONMENT

In this study, temperature of an uninsulated environment was controlled by PID for on-off and various parameter values using Arduino micro controller. A medium with high heat transmission and with no insulation materials on the junctions and the surface to prevent heat transfer into the external environment, is heated by an AC voltage-operated resistor. Temperature of the heated environment is taken with LM35 temperature sensor and converted to 0-10V industrial standards. Temperature information converted to voltage value was applied as an analogue input to the Arduino Due micro controller and resistance voltage was set via semiconductor switching path as a result of PID operation. Despite deteriorating experimental results such as heat loss, it is seen that the reference temperature is captured by the PID.
