IoT Based Indoor Air and Water Quality Monitoring System Using Node-RED

Indoor air and water quality play a significant role in our health and well-being. An indoor air and water quality monitoring system is a device that measures and analyzes the quality of indoor air and water to ensure that they are safe and within acceptable limits. This paper presents the design and development of the system that uses sensors to sense the presence of harmful gasses and compounds in the air, conductivity of water while constantly transmitting this data to a microcontroller, ESP8266. This project is addressing the issue of indoor air and water quality using the internet of things communication model. Specifically, the system measures the real-time for both quality data by detecting the level of air and water parameters in the allocated area. The system contains sensors to detect various parameters such as temperature, humidity, carbon dioxide, volatile organic compounds, and particulate matter. It also incorporates a water quality sensor to detect temperature, salinity, and pH value. The system is designed to help individuals and organizations maintain a healthy indoor environment and reduce the risk of health problems associated with poor indoor air and water quality. The Node-Red is used as the Internet of Things (IoT) platform/server to receive signal and data from the ESP8266. The monitoring system provides the pollution level data in closed areas while notifying the users via Telegram application as an alert system.
