MATERIALS AND METHODS
The Chapter III contains the Research Methodology, which includes: Research Design,
Procedure of the study ,conceptual framework and project design model.
RESEARCH DESIGN
The researcher aimed to develop and evaluate a the Micro Controller Unit-Based
Monitoring Device For Air Pollution Level. To attain the objectives of the study, the
developmental descriptive method of research was used.
This study utilized developmental researcher throughout the conduct of the study since
the current study made use of the locally available and low cost materials to construct a the
Micro Controller Unit-Based Monitoring Device For Air Pollution Level. The device was also
developed and constructed to monitor the harmful gases present in the ambient such as Carbon
Monoxide that causes diseases and to be used as a source of information to people exposed in the
car parks which contains high level of CO gases.
METHODS OF THE STUDY
This shows the methods that the researchers used to developed and construct the Micro
Controller Unit-Based Monitoring Device For Air Pollution Level.
CONCEPTUAL FRAMEWORK
