Abstract
Abstract Toxic and Combustible gases are one of the most notorious killers of Oil and Gas Industry (OGI) workers. Hardly can one find an accident in which they are not involved, as such governments around the world enforce the use of gas sensors in all works that are related to these gases. Until recently, wired gas sensing systems are used. Although, they are rugged and reliable, they are expensive to install and maintain. Wireless gas leakage detection systems are flexible, easy to install and maintain. However, gas sensors tend to consume lots of energy, while those that consume less energy are not accurate. In this paper, an experimental research is carried out to investigate the energy performance of a Zigbee Wireless Sensor Network (WSN) made up of wireless sensor nodes and industrial-grade gas sensors to create a Wireless Gas Safety and Monitoring System (WG-SMS). The system uses careful combination of energy harvesting, sensor node role assignment and adaptive sleep cycle to achieve maximum attainable lifetime by saving 60% more energy.
