Abstract

The title of this Final Year project is 'The Design of Humidity Control Chamber'. This system is created initially to provide a proper environment for the sensor to work; the idea has been expanded so that it can be used as a humidity control chamber. By providing different levels ofhumidity, user will get to choose and set the required humidity level in the range from 0 to 99%RH. To offer these useful functions, the system has been built as a combination of a water bubbler system, test chamber, valve system, and proper tubing; all are controlled by a pre-programmed PIC microcontroller. A standard relative humidity sensor is located inside the chamber to provide inputs to the PIC. Current percentage of relative humidity and temperature will be displayed by LCD Display connected to the PIC. An electronic keypad will be connected as the interface for users to key in inputs. The test system is then to be connected to dry air supply to start functioning as needed. The project has been started with literature reviews on the basic concept of humidity, the importance and current market trend, with sets of experiments done to strengthen the fundamentals during Final Year Project 1. During the second semester, the focus is more on the compact, portable and practical design of the system. The controller circuit is then constructed and connected to the mechanical parts so that the whole system can work automatically the moment an input from used is received.
