Some of the world's biggest problems, such as climate change and pollution, are being addressed, along with the management of finite resources, by environmental monitoring. However, there exist a huge number of existing IoT-based environmental monitoring systems, which cannot be put into use due to high prices, lack of sensor integration, and poor data processing in a large range of industries. This paper reports a low-cost, scalable, and comprehensive IoT-based environmental monitoring system that has been designed using Atmega 2560 microprocessors along with ESP8266 Wi-Fi module. DHT11 sensor has been included for supporting temperature and humidity, whereas BMP180 and MQ-2 have been utilized for sensing light intensity and atmospheric pressure, respectively. Additionally, MQ-135 sensor for gas sensing, Rain Sensor for identifying rainfalls, and Dust Sensor for quantifying particulate matter, have also been integrated within the proposed framework. With the Atmega 2560, it is possible to capture sensor data simultaneously. The ESP8266 ensures that the data is transmitted wirelessly to a web-based dashboard using the HTTP protocol. This dashboard provides real-time environmental information for instant decision-making on issues about agriculture, smart cities, and industrial facilities. This system differs from the previous alternatives because of its low cost, scalability, and simplicity in implementation, which makes it highly applicable to large-scale environmental monitoring applications.
