Voice-Controlled Smart Home Prototype to Assist an Elder in Home Care

This research aims to create a prototype of a smart home system to assist an elder in a home care scenario. Smart home system users can control devices such as lights using voice commands, keep track of the users heart rate, monitor house situation, and store users events using a schedule reminder. The smart home system will use Raspberry Pi 3 as the main microcontroller, Wemos D1 as a microcontroller on the smart home model, Broadlink RM Mini 3 as the medium to control an air conditioner and television, and Xiaomi Mi Band 2 as the wearable device. The program will use the Node-RED, NORA, and Firebase platforms which are very helpful in the development of the Internet of Things. System testing is done by testing the features of smart home systems, wearable devices, schedule reminders, as well as surveying the level of user satisfaction. The test results show that the smart home system can function properly. The microphone can detect voice commands up to a two-meter distance. Broadlink is able to control devices up to a threemeter distance. Wearable devices have succeeded in measuring the users heart rate up to a distance of 9 meters, whereas the schedule reminder manages to store user events. Additionally, survey results indicate that respondents are satisfied with our system features.
