Mobile IoT Solution for Monitoring Air Quality

Our Development Process

• FIRMWARE DEVELOPMENT

  The team designed the platform based on the ESP32 system-on-chip and a set of sensors capable of transmitting data to the cloud via Wi-Fi. The platform is equipped with firmware developed using the PlatformIO toolset for embedded C/C++ development. The firmware collects data from sensors that measure air temperature, relative humidity, pressure, VOC levels, and carbon dioxide levels, and transmits it to the cloud using the MQTT protocol.

• UX/UI DESIGN

  Indeema's design team developed wireframes for the UBreez application. The team employed a user-centric design approach to craft an intuitive and user-friendly interface. After finalizing the design concept, the team created high-fidelity mockups for the UBreez application, with a focus on delivering a sleek and contemporary design that maintains consistency across all screens and platforms, including Android and iOS.

• WEB DEVELOPMENT

  Drawing from the insights gathered during the discovery phase, Indeema's development team carefully chose the technology stack best suited for the project. They opted for Node.js for the backend and selected React.js, HTML, and CSS for the front-end. The backend development team prioritized the creation of a secure and scalable infrastructure.

• MOBILE DEVELOPMENT APP TO MEASURE IAQ CASE STUDY

  After considering several options, the team decided on the cross-platform Qt framework. The decision to use the Qt framework was motivated by the need to create mobile apps for both iOS and Android without having to write separate code for each platform. The framework's capacity to facilitate code reuse across various operating systems, thus minimizing development time and costs, played a pivotal role in the decision-making process.

• DEVOPS AND CLOUD ENGINEERING

  The DevOps team was responsible for designing and implementing a cloud infrastructure for the Ubreez platform. They utilized Amazon Web Services (AWS) to construct a scalable and secure cloud infrastructure that would empower the client to collect, store, and analyze real-time air quality data. Specifically, the team harnessed AWS services, including EC2, S3, RDS, and Lambda, to establish a reliable and scalable cloud infrastructure. Additionally, they employed GitLab CI/CD to automate the deployment process, ensuring that updates were delivered swiftly and efficiently.

• TESTING & QUALITY ASSURANCE

  The testing process involves verifying the functionality and performance of every component of the IoT product, including the UBox device, cloud platform, and UBreez application. Each component undergoes a series of manual tests, encompassing functional testing, integration testing, and system testing. The QA team has confirmed that the IoT product meets both functional and non-functional requirements, ensuring its reliability, security, and scalability.

• LAUNCH

  Following the release of the Ubreez project, the development team recognized the importance of gathering user feedback to ensure that the app met user expectations and functioned optimally. To achieve this, the team conducted user testing to collect data and identify areas for improvement. The user testing process took place in several stages, commencing with an initial beta release distributed to a small group of users. These users were requested to provide feedback regarding the app's functionality, ease of use, and overall user experience. Based on the feedback received, the development team identified the need to create a comprehensive set of guidelines for users, ensuring they could fully leverage the app's functionality.

• MAINTANCE

  During the maintenance stage, the development team identifies and rectifies any bugs that may be impacting the UBreez product. Additionally, regular updates to the UBreez application are carried out to enhance its functionality and address potential security vulnerabilities.
