Abstract. Boiler smoke emissions contain carbon monoxide (CO) gas which can pollute the environment and endanger human health. This study aims to design an Internet of Things (IoT)-based CO gas filtration system to monitor gas levels in real time. The system uses an ESP32 microcontroller, two MQ-7 sensors to detect CO levels before and after filtration, a relay and exhaust fan for air circulation control, as well as an I2C LCD and Blynk application for monitoring media. The system works by detecting CO gas levels in boiler smoke. When the gas level increases, the exhaust fan automatically turns on to assist the filtration process. CO gas levels and filtration efficiency data are displayed in real time through the LCD and Blynk application. The test results show that the system is capable of monitoring and controlling CO gas emissions properly and reducing gas levels after the filtration process.
