Cigarette Smoke Detectors for Non-Smoking Areas in the Building

This Research aims to study and design cigarette smoke detectors for Non-Smoking Area in the building. In order to be used to detect smoke in various places. The design of the smoke detector is designed by the Gas Sensor (MQ-2) detect smoke and NodeMCU V2 (ESP8266-12e) to store the value of the sensor as a voltage. When the sensor detects fumes until the voltage is exceeded, NodeMCU V2 (ESP8266-12e) will and send a message to the administrator pushes notifications through LINE API on the LINE Application. From Experimental Summary the cigarette smoke detectors in this developed area. It is a system that can detect smoke in the area of not more than 20 square meters (m2) and a room height of not more than 3 meters (m) if the room width and height. The device can detect smoke in a short time and can send a message. Remind staff at the building to be aware that a person is smoking in a smoking area.
