Week 1

Week 1: Software & Hardware Development

Software Team

Pre-Lab Activities:
At the beginning of the week, following our supervisor meeting on Monday, the team held a discussion to define the main functional requirements of the project. We also developed a preliminary technical architecture, outlining the key components and their interactions within the system.

Lab Session (Thursday):
During the lab, we conducted further research on the components used in our system to refine our technical understanding and validate the feasibility of our proposed architecture. This process helped ensure that our system design met the intended functional requirements.

Temperature and Humidity Sensor Analysis:
One of the key components in our system is the temperature and humidity sensor. This sensor operates by utilizing a moisture-sensitive substrate positioned between two electrodes. As humidity levels rise, the substrate absorbs water vapor, releasing ions and subsequently reducing the resistance between the electrodes. This change in resistance is directly proportional to the relative humidity, allowing for accurate measurement.

A detailed specification analysis of the sensor was conducted, and its performance characteristics were reviewed to ensure compatibility with our system requirements. The graph below illustrates its response characteristics under varying environmental conditions.

Hardware Team

Nebulizer Integration and Power Setup:
During the first week, our focus was on integrating the nebulizer unit into the system. We began by working with a 12V adapter, carefully soldering the wires to ensure a secure and reliable connection. These connections were then interfaced with a breadboard, allowing for efficient power distribution to various components of the humidifier system.

This foundational work ensured that the power supply and nebulizer unit functioned correctly, forming the basis for further hardware integration in the following weeks.
