Detection of cigarette smoke is very necessary to increase the level of comfort in a closed room. By implementing an Internet of Thing system in detecting cigarette smoke in the room, making it easier to monitor and control it via a smartphone. In this system, the MQ-2 sensor is used to detect cigarette smoke in the room, the NodemCu microcontroller as a data processor received from the sensor, the buzzer as an indicator sound and the blynk application to display notifications if the room is detected by cigarette smoke. The sensitivity level of the MQ-2 sensor is strongly influenced by the distance of the source of cigarette smoke with the sensor. The use of the internet of thing system affects the signal strength and network on the user’s smartphone which results in a delay when sending notifications. Therefore, a good internet network is needed. The use of IoT technology in detecting cigarette smoke in a room will be an alternative solution to increase the level of security and comfort in a closed room.
