The project, Innovative Controller for Home Security and Monitoring System (iCon) is a small and compact and affordable home security and monitoring, interfaced with the PC via designed interface, and added with additional data logging features. This data-logging feature is not only recorded on Personal Computers. In the case of power failure or PC failure, data logging is done simultaneously on the memory card, allowing users to monitor the condition or status of the sensors based on the time set by the Personal Computer. The initialization of the Real-Time clock of the memory module is done beforehand. A variety of commonly used sensors are attached to the system controller, namely the magnetic door sensor, the motion sensor, shock sensor, temperature sensor, humidity sensor and smoke sensor. These vital sensors are attached and any over-limit of the sensors will be detected by the controller, and then sent to the PC and memory card for data logging. When the conditions are secure or the sensor returns to normal conditions, the data is also saved. As an added feature, a GSM is attached to the system, allowing any information on abnormal conditions sent to the user???s mobile phone and the user can control the system via SMS.
