Abstract

This simple door-opening alarm uses a hall sensor to produce sound when someone opens the door. The circuit can be installed at a workshop, office or home for security purposes. The 3-terminal hall sensor is easily available in the market. The door alarm system is an electronic device that can be used as a security device. It is an electronic watch dog, because when installed to a door, and somebody touches the door, it sounds an alarm. The unit is built from discrete semiconductor device. It is relatively simple in both its operation and analysis. One particular feature of this project circuit (the door alarm system) is its versatility. The circuit can be adapted for other applications. All the Information necessary for its realization is contained in this project write-up. Chapter one contains the introduction to the door alarm system, Chapter two contains the circuit analysis and component review, Chapter three contains the research and methodology adopted, Chapter four contains the design and construction while the work was concluded in project.
