Cigarette smoke in smoking areas can significantly reduce air quality and increase health risks for occupants. Conventional exhaust fans that are operated manually are often ineffective and consume electrical energy inefficiently. This study aims to design and develop an Internet of Things (IoT)-based automatic exhaust fan control system using the ESP8266 microcontroller to improve air circulation and monitor electrical power consumption in real time. The system integrates an MQ-135 sensor to detect air quality, a DHT11 sensor to measure temperature and humidity, and a PZEM-004T sensor to monitor voltage, current, and power usage. Sensor data are processed by the ESP8266, which controls a relay to automatically activate the exhaust fan when air quality exceeds a predefined threshold. All monitoring results are displayed through the Blynk application. Testing showed that the DHT11 sensor achieved 98.33% accuracy, and the system effectively maintained air quality while reducing energy consumption compared to conventional ventilation
