Negligence or failure to detect gas leakage from LPG cylinder in kitchen may lead to dangerous situations. Several accidents due to gas leakage at homes have been reported. A need also exists for early detection of gas level for ordering cylinder refill. The objective of the study is to design and develop a Wireless Sensor Network (WSN) (radio frequency) based gas leakage detection and gas level monitoring for smart and safe home. The system detects the leakage of the LPG and alerts the user using buzzer and LEDs. It continuously monitors the level of the gas present in the cylinder using load sensor and alerts the user when the cylinder level goes <25%. A prototype has been developed for gas leakage detection and level monitoring and tested. The tests results confirmed the satisfactory performance of the system developed. The proposed design ensures safety and prevention of accidents due to LPG leakage in smart homes. This also alerts the consumer when the gas level falls below 25%.
