In today's rapidly changing digital world, smart home automation has become increasingly popular. It has revolutionized house systems and improved comfort, efficiency, and safety, especially for the elderly. For senior citizens, keeping a home safe at each level is very important to avoid any type of hazards. In this paper, a home automation system has been developed focusing on affordability and safety. Using microcontrollers such as NodeMCU, Arduino UNO, several sensors and mobile applications, a smart home automation system has been built to ensure the safety of a home at a low cost. The Internet of Things (IoT) has also been introduced in this system which gives the power to operate electrical appliances using smart devices. The proposed home automation system redefines contemporary living standards by integrating safety assurance into daily activities and boosting comfort and security. After installing important sensors, testing, and connecting through the internet, the proposed system can ensure a secured smart home with an affordable budget for the elderly. This system has worked greatly in making a home smart and safe. The system provides its services to the user when they are at home as well as away from the home. Specially, this system ensures the safety and security of the home by sending immediate notifications and alerts to the user if any inconvenience happens in the house such as fire and gas leakage. By monitoring the presence of someone when they come in front of the door, the system also notifies the user through a message or email.
