A wireless safety device for gas leakage detection is as important as life itself. The device is for use in household safety where appliances and heaters that use natural gas and liquid petroleum gas (LPG) may be a source of risk. The system also can be used for other applications in the industry or plants that depend on LPG and natural gas in their operations. The system design consists of two main modules: the detection and transmission module, and the receiving module. The detection and transmitting module detects the change of gas concentration using a special sensing circuit built for this purpose. This module checks if a change in concentration of gas(es) has exceeded a certain predetermined threshold. If the sensor detects a change in gas concentration, it activates and raises alarm of up to 85 decibel. The system was tested using LPG and the alarm was activated as a result of change in concentration.
