I. Introduction
Pollution is a major concern in cities and companies nowadays. The rapid increase of companies, infrastructure, and transport vehicles has produced environmental challenges, including the greenhouse effect and illnesses caused by toxic gases, which directly affect human health and need a particular monitoring system [1]. To reduce environmental pollution, we use IoT-based pollution monitoring and control systems. That identifies harmful gases in the environment. Using Raspberry Pi and sensor technologies, the proposed IoT solution monitors industrial CO2 emissions, temperature, and humidity. Data monitoring and control will be independent for each process. This device will be connected to a Blynk server mobile app that displays real-time environmental pollution levels in industry and rural areas. IoT aids remote knowledge access.
