development of a GSM based power management system. This system allows monitoring and control power consumption by household appliances. The GSM technology is well deployed in most developed countries due to its features like easy interfacing with appliances via radio frequency‚ accessibility at remote area. In this paper‚ software and hardware were developed. The software allows the user of the system to request for an action from the hardware components. The micro-controller is connected with GSM and relays
