Abstract
Open loop control system is the type without feedback, that is, no sensor sensing the control variable, hence works on time basis. The paper established the facts that the system will prevent ubiquitous fire incidences associated with electric stoves and other heating devices. It describes the application of simple electronics circuitries in designing the low cost Cooker Control Device. The building blocks of the unit were designed one after the other using preferred components available in the local markets. The project was wired on Breadboard. The board permits the design to be tested without employing soldering processes. The design enumerates some important construction precautions which are further accentuated with the inclusion of various tips on healthy soldering processes. It is believed that the unit will prevent fire incidences associated with electric cooker. Simple explanations given to drive home power electronics principles used and copious illustrations rendered will make the innovative and ingenuous enterprise interesting to power electronics enthusiasts and other professionals alike. The paper recommends incorporation of embedded system with Liquid Crystal Display in the future design improvement.
