Rancang Bangun Sistem Pembuangan Asap Rokok Pada Smoking Room Berbasis Arduino
ABSTRACT
The disposal of cigarette smoke in a closed room works when cigarette smoke is
detected by the MQ 2 sensor, processes data to the Arduino Uno and gives a
signal to the relay and turns on the dc fan automatically. When the MQ 2 sensor
detects smoke and the ppm value is above 40 ppm which is displayed on the 16 x 2
LCD, the fan automatically activates to remove the smoke in the closed room and
so the ppm value drops on the 16 x 2 LCD to be safe or 0 ppm
