ABSTRACT At present gas leakage becomes a serious problem in household, gas vehicles and industries. Gas leakage leads to various accidents resulting into both financial loss as well as human injuries. In context with these issues, the proposed design is able to detect and control gas leakage. The system detects gas leakage and alerts the subscriber through SMS, alarm and display unit. Simultaneously as primary safety, it will turn off the gas supply and power supply of the respective area. The system uses GSM module for sending SMS and stepper motor is used for turning off power supply and gas supply. The proposed work utilizes RF link send an alert to the consumer and neighbors through alarm. The system not only takes the corrective action but also confer the gas re-setting of the system. The additional advantage of the system is that it continuously monitors the level of the LPG present in the cylinder using weight sensor and automatically books the cylinder using a GSM module.
