Integrated Environmental Monitoring and Disease Detection Using Internet of Things

This project presents an integrated environmental monitoring and disease detection system using the Internet of Things (IoT), aimed at real-time tracking of air quality and environmental parameters to support public health. The system utilizes an MQ135 gas sensor to detect harmful gases, a DHT11 sensor to monitor temperature and humidity, and a PMS sensor for particulate matter detection. These sensors are interfaced with an Arduino microcontroller, which processes the data and activates a buzzer alert when any sensor readings exceed predefined threshold levels, indicating potential health risks. Simultaneously, a GSM module is triggered to send an SMS alert to predefined recipients. The collected environmental data is transmitted wirelessly to the ThingSpeak cloud platform via a NodeMCU module for remote monitoring and analysis. An LCD is included to display real-time sensor values locally. This cost-effective and scalable system can be deployed in homes, schools, and urban areas to help detect disease-prone environments early and mitigate health hazards.
