    An Improved GSM Technology-Based Microcontroller Multi-Sensor Home Security and Monitoring System
    (International Engineering Conference (IEC), School of Engineering and Engineering Technology (SEET), 2015) Oyewobi S. Stephen; M. Okwori; E. U. Mpkuma; W. M. Audu
    With increasing rate of crime all over the world, and with no pointer to this rate of crime abating anytime soon, home security has now become a major concern. Therefore most people; rich or poor are taking measures from highly sophisticated to very crude methods to prevent intrusion. This work presents a GSM technology-based home security and monitoring system. However, unlike the traditional magnetic switch alarms equipped on doors and windows, this system has incorporated a fire detector, a motion sensor and a moisture (rainfall) sensor. On any attempt of a break in, rainfall or possible smoke or fire a short message service (SMS) is sent to the house owner. The system is built using a programmed microcontroller interfaced with mobile phone (NOKIA 1209) such that the three major buttons of the mobile phone are switched at intervals to send a message to the owner of the house anytime there is an intruder, rainfall or fire accident. The system was tested and it worked on attempt of intrusion, rainfall (water) and smoke.

    Development of Feedback Mechanism for Microcontroller Based SMS Electronic Strolling Message Display Board. African Journal of Computing & ICT
    (African Journal of Computing & ICT, 2014-08-12) Dogo, E.M., Akogbe A.M., Folorunsho, T. A., Maliki, D., & Akindele, A
    Digital electronic display board is fast gaining acceptance and application in different spheres of life which include educational education institution, public utility places and in advertisement due to the problem associated with constitution of signposts and manually placement of papers on walls, buildings, and edifies which makes the environment look untidy. This paper presents the design and development of a microcontroller based electronic strolling message display board, which will be used to display messages and information in real-time via SMS. This microcontroller based electronic strolling message display board offers the flexibility to a user to control the message or information displayed without recourse to geographical location of the user, provided there is GSM (Global System for Mobile Communication) mobile network. It therefore eliminates the inconveniences of physically going to the display board to manually input information using a computer system. The paper also incorporates a feedback mechanism from the remote display board to ascertain that the message sent by the user has been displayed. The circuit of the devices is designed based on PIC18F4520 microcontroller and C-programming language is used to program the microcontroller.
