Indoor areas in healthcare environments, particularly emergency areas, MRI, and CT scan rooms, are often exposed to various pollutants and contaminants, including bacteria and viruses. Monitoring air quality has become a crucial agenda for these spaces. This study develops a system using an ESP32 microcontroller, MQ-135 and MQ-2 gas sensors, and IoT applications for real-time IAQ monitoring. Data is transmitted via Wi-Fi to a Blynk dashboard for visualization and user notification, including email alerts and alarms to operate the disinfectant. The results show the system's effectiveness by using alarms to promptly notify users via email about significant differences in Indoor Air Quality (IAQ) across different settings. This cost-effective solution has great potential for use in healthcare environments to enhance safety and comfort.
