Abstract
This paper proposes a solution to enforce the Smoking-Free Area Regulation in Universiti Teknologi Malaysia (UTM) through the product called Smart Smoke Alarm System which can prevent smoker smoking in the campus area. When the sensor detect dangerous level of smoke it will immediately triggers an alarm sound along 5 minutes alert user through mobile application. Multiple users can receive alerts to gives the user controls the device wherever you are and can have multiple devices on each account. At present, the system only can be connected to one device of smoke detector and will triggers alarm when the amount of smoke detected. User will get a notification through the mobile application and give control whether to put off the alarm or inform to the other user respond to the situation.

Introduction
Smoke Alarm System (SAS) is a device that detects any kind of smoke and will notify alarm alert to user when there is potential of fire occurs. The concept of Internet of Things (IoT) is applied to this project. Smoke detector circuit is develop using Arduino UNO connected with WiFi board based ESP-8266 WeMos-D1R2 mini and gas sensor MQ-4 while the mobile application is develop by using MIT App Inventor. When SAS detect amount of smoke at surrounding it will notify user through mobile application. For additional function, SAS can detect temperature and humidity of surrounding.
