3 As a solution for the problem, a monitoring system of gas detector by wireless system needs to be developed in order to solve the problem. By monitoring system wirelessly, user can remotely view the condition of the room or office without them being there themselves. 1.3 Objectives of Project The objectives of this project are: i. To analyze gas sensor in detecting the LPG and alcohol gas based on the two gas sensor. ii. iii. To design gas control system that shows the indicator alarm to the user. To develop a system that can automate monitoring using LABVIEW. 1.4 Scopes of Project This project are divided into software programming and hardware. For the hardware, it can be categorized into four systems: i. The sensing system ii. Arduino Uno Board iii. Output system
4 iv. Zigbee Arduino Uno is a device that acts similarly to a microcontroller unit. In this project, Arduino is the perfect microcontroller due to its high performance and special features. The Arduino Uno is an open-source electronic prototyping platform based on flexible, easy-to-use hardware and software. Further explanation on this unit is discussed in chapter 2 and 3. The sensing circuit system consists of Liquefied Petroleum Gas (LPG) sensor, MQ 6 and alcohol gas sensor, MQ 3. These sensors are used to detect the presence of specified gas in the surroundings area. The output system consists of LEDs, buzzer and exhaust fan. Zigbee or xbee will transfer sensor data read from Arduino port to a computer in a wireless connection. The software design are divided into three parts that are: i. Arduino programming ii. Zigbee programming iii. LABVIEW design Arduino software is used to write the programming for the Arduino board microcontroller. On the other hand, X-CTU is used to program zigbee in order for the data to be transferred. Meanwhile, the LABVIEW Graphical User Interface (GUI) is used to monitor the level of gas concentration.
