Further details regarding the Internet of Things (IoT)-based indoor cigarette smoke monitoring and disposal tool that has been developed by the author.The main component of this tool is the ATMega328 Microcontroller which acts as the main controller of the tool.The ESP32 microcontroller is used for remote monitoring and control via the Blynk application on a smartphone.The MQ-2 sensor is used to detect the presence of cigarette smoke in the room, the Buzzer functions as an alarm that will sound if the smoke level exceeds the threshold.The LCD screen displays the ppm (parts per million) value of smoke in the room.The exhaust fan functions to expel smoke from room.By using IoT technology to allow users to view and control tools remotely via the Blynk application on their smartphone.The operating mode in this tool uses two modes, namely automatic mode and manual mode where the automatic mode will work.If the MQ-2 sensor detects smoke levels exceeding the limit, the buzzer will sound as a warning, and the exhaust fan will be activated to clean indoor air automatically.Manual mode, here users can control the exhaust fan remotely via the Blynk application on their smartphone.
