IoT based applications for healthcare and home automation

Abstract

The Internet of Things (IoT) is a paradigm that involves connecting the virtual world of the Internet to the real world through so-called smart objects. Indeed, Internet of Things (IoT) devices are extensively employed in a wide range of applications, including healthcare field and home automation. These objects are equipped with communication capabilities and can exchange data over the Internet. In recent times, the healthcare sector has witnessed a surge of growth and transformation. The integration of IoT-enabled devices has revolutionized remote monitoring in healthcare, empowering healthcare providers to keep their patients safe and healthy while delivering exceptional care. On the other hand, the home automation system is becoming increasingly popular due to its many benefits, which involve remotely monitoring and controlling household appliances. In fact, the main challenges faced by home automation systems are poor manageability, rigidity, difficulty in achieving security, and high ownership costs. As the internet and its applications continue to grow, there is enormous potential for remotely accessing, controlling and monitoring network-enabled devices. With this context in mind, the objective of this project is to develop two IoT-based models. These models are based on Arduino and Raspberry pi boards, cloud, Bluetooth and ZigBee protocols. The first model is an IoT healthcare system that employs various sensors to collect heart rate and motion data. The second model is a home automation system that utilizes a DHT11 sensor to measure temperature and humidity levels, a MQ2 sensor to detect gas leaks, and an ultrasonic sensor to control the garage door's opening and closing. Both systems are built around an Arduino or a Raspberry pi microcontrollers integrated with an Android mobile application to process and transmit data via Bluetooth or Zigbee ensuring that the mobile app receives real-time updates.
