Abstract: Gas leakage detection and monitoring through sensor network is considered to be more economical for industries gas leakage. Main purpose of this system model is to avoid damages and safety of gas industry. The entire control system is based on low power AT89c51 microcontroller and GSM/GPS techniques. The sensor and micro-controller node helps in collecting data regarding gas leakage and the particular area of sensor node address is located. The collected information is sent to the monitoring client or user to update the data. Data packets are continuously transmitted from sensor nodes and communication devices. This system helps to minimizing human intervention and reduces power consumption, thus providing greater performance. This paper not only focuses on alerting but also to control the leakage under certain circumstances. Hence several interfaces such as LCD, stepper motor, servo motor, Exhaust fan, GSM/GPS are done for effective functioning. This paper focus on overall modelling and design on both software and hardware part to accomplish it.
