The aim of the project is to develop a gas leak detection and location system for the production safety in Petrochemical Industry.


The purpose of the project is to monitor gas leakage parameter. When they exceeds threshold, intimation is given to the nearby control section including readings of parameter and location of the gas leakage.


The system is based on Wireless Sensor Networks (WSN) it can collect the data of monitoring sites wirelessly and sent to the computer to update values and the location also.

Consequently, it can give a real time detective of the potential risk area, collect the data of a leak accident and locate the leakage point. However the former systems cannot react in time even cannot obtain data from an accident and locate accurately.

The paper has three parts, first, gives the overall system design, and then provides the approaches on both hardware and software to achieve it. The gas leak detection and location system consists of three parts: control center and terminal nodes.

Here the supervising control center is based on arm controller, it displays the location and the status messages of parameters of all the monitoring sites, and it is a graphical description of the geographical information of the entire potential risk area. Status, sensor data and location data, and then sent them to the control center to update value in the location software


Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the wide range controlling applications and to replace the existing non-standard technologies.

It currently operates in 868 MHz band at a data rate of 20Kbps in Europe, 914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps. It is used to verify whether user's truncation is possible or not.

One of the main advantages of this ZIGBEE communication is that it provides a noise free communication, the amount of noise added in this type of communication is very less compared to the other wireless communications


Hence a gas leak detection and location system for the production safety in Petrochemical Industry was designed.
