BreatheFree – A Smart Inhaler for a Smart, Safe & Healthier World

Chronic obstructive pulmonary disease (COPD) and asthma have been shown to be on the rise daily as a result of a variety of causes, including smoking behaviours, the use of dirty fuel for cooking, ageing, atopy-related family history, asthma history in a first-degree relative, air pollution, etc. It has been discovered that every two out of every three asthma sufferers have frequent asthma attacks, many of which are unplanned, deadly, and need for immediate medical attention. This highlights the necessity for technology to monitor the environment for the presence of triggers and avoid asthma attacks. The project's goal is to create a preventative tool that may aid patients by warning them of any improper circumstances that can trigger an asthma attack. In order to monitor the environment and gauge the existence of triggers that are invisible, the project employs a collection of gas sensors. The microcontroller analyses the detected data to calculate the concentration of the allergen trigger before transmitting it over Bluetooth to the Android application. The Android app presents the information visually and alerts the user to any allergen concentrations that might be dangerous, assisting patients in taking the appropriate preventative measures to avoid triggers.
