Smart Magnetic Door Lock For Elderly People Using AWS Alexa, IoT, Lambda and ESP Module

Abstract

Purpose: Nowadays, we all are busy. From morning till night, we spent most of our time outside the house. In most of the scenarios, we struggle to fulfill our financial needs. We are bound to keep our senior citizens at home, and we are busy with work, which provides us assurance of financial health. Our senior citizen is engaged to manage the house. They are generally involved with lightweight tasks like opening the main door. But this work sometimes causes trouble for our older people if they have difficulty walking. Sometimes, they need to come from upstairs to down. For this problem, we have a solution. Without coming downstairs or in front of the main door, we must say, “Alexa, open the door” from a mobile phone. The door will open. After that, it will also lock automatically. There is no need to shut the door again. Design/Methodology/Approach: We execute the project using AWS IoT, Lambda, and Alexa voice service. We create our IoT profile inside the AWS cloud. Create and upload Lambda functions to the AWS Lambda cloud services to trigger the equipment. Create Alexa skills inside the Alexa developer console to convert voice commands into text. Findings/Result: After executing several experiments, we observed that our system ran well without any false triggering. We also observed that the system performance is good if the internet is speedy enough and the voice is clear and electronically understandable. Originality/Value: Much research has been done on automatic door-opening systems for older adults. But most of the architecture is less feasible for daily hassle-free use. So, considering all aspects like consistency, security, robustness, and fast response, we decided to implement this architecture, which we can say is a unique approach and provides value to the user’s daily life. Paper Type: Experimental-based research
