The global system for mobile communications-based home monitoring system (GSM-HMS) was developed with the aim of developing a prototype that can control multiple inputs through the Short Message Service provided by GSM networks. A 28 Encore! 1 microcontroller was used to interface with a Nokia 63102 via its UART feature. The 28 Encore! also handles signals received from various sensors and controls relays and motors installed throughout a small-scale house that was designed specifically for the study to simulate everyday conditions. C-based software was written to handle AT commands used to communicate and control the Nokia 6310 while also maintaining a database of execution sequences that the user can request and keep track of the various items monitored and controlled by the GSM-HMS. Through this, the system monitors and updates the user of the status of each element it oversees and is able to execute pre-defined commands received through SMS. This allows the user to open the windows, close an appliance or turn on the lights even from a remote distance using SMS. The GSM­HMS can communicate with anyone provided that the user has a GSM phone on hand with an optional password authentication feature that can be disabled when using the default number recognized by the system. The system operates in two modes -when the user is present and is away -with each mode providing a different level of security.
