AWS IoT integration

The world today is witnessing a growing trend in the use of technology in the health sector. This gave us an opportunity in assisting our client, a pharmaceutical company in tracking medical devices and the quality of medicines on the go along with the inventory and transit status.In this case study we discuss:

  • How we implemented a small IoT application with a toolkit to assure product quality, elevate efficiency of medical devices and raise alert in case manual intervention is required
  • Set up AWS for the application in order to manage the devices seamlessly
  • Interaction with the device to fetch vital information
  • Finally creating a mobile application and using AWS IoT to monitor the devices

Solution

We used the below solution components to create a responsive web application which gives a holistic view of all the devices connected to the system as well as information on their vital parameters. 

  • Creating screen design using SAP Build on Fiori Guidelines.
  • Raspberry Pi3
  • Humidity and Temperature sensor to be added
  • Using AWS IoT core functionality.
  • Responsive web application
  • Backend in Azure
  • Coding in C#, JavaScript and Angular 5 using Fiori guidelines
  • Using MQTT to receive data

Challenges

We encountered some issues as below: 

  • AWS setup and pricing was complicated to understand as it is based on usage and consumption which was a difficult thing to assess at the start of application
  • Ensuring data privacy and security is of utmost importance in this case. Since devices can be hacked without much effort due to poor encryption and that could allow unauthorised access
  • Impeccable quality assurance of the whole set up was to be achieved in this case of pharmaceutical industry which involves dealing with medicines are surgical instruments so there was a need for real sharing of information if anything was not going as expected 
  • It was difficult to understand the client vision of how they needed the UI.

Results

Accomplishments

  • IoT opens newer technological possibilities by connecting devices and serves applications to make services like healthcare accessible remotely, enabling proper utilization of resources(medical devices in this case) through real time monitoring and control with the help of technology.
  • Learning and Using AWS IoT platform is a secure way of connecting with devices to bring in efficiencies and cost savings through regular and remote monitoring, timely maintenance of the same, and the ability to perform quick and informed decision making while reducing response time and wastage of medicines
  • Making data available in real time and creating a responsive web application which leverages the same and provides ease in real time monitoring of devices and medicines(measuring parameters and highlighting changes). This brings in visibility and transparency in the process and reduces the error rate and dependency on human intervention to track the same
  • We also added a reporting and capability management mechanism to ensure the client could get a good historical overview of how the system is performing
  • UI designs were implemented first as a high fidelity mockup and later as a responsive web application on the client's intranet

                      Deliverable:

  • Responsive web application
  • Login mechanism using 2 Factor authentication
  •  Integration with AWS IoT to send and receive data
