Leakage of gas is a major issue in the industrial sector, residential buildings, and gas-powered vehicles, one of the preventive methods to stop accidents associated with gas leakage is to install gas leakage detection devices. The focus of this work is to propose a device that can detect gas leakage and alert the owners to avert problems due to gas leakages. The system is based on a microcontroller that employs a gas sensor as well as a GSM module, an LCD display, and a buzzer. The system was designed for gas leakage monitoring and alerts with SMS via an Arduino microcontroller with a buzzer and an MQ2 gas sensor. The circuit contains a Microcontroller MQ2 gas sensor, buzzer, LCD display, and GSM module, when the sensor detects gas leakage it transmit the information to the Microcontroller while the microcontroller makes a decision and then forwarded a warning message to the user as SMS to a mobile phone for decision to be taken accordingly. The output of this research will be significant in averting problems associated with gas leakages now and in future. 

Open Educational Resources (OER) are those teaching and learning materials that are available either in the public domain or under an open license. The focus of this research work is to propose a conceptual framework for design and implementation of TVET autonomic cloud-based OERs for it integration into classroom teaching and learning strategies towards sustainable development. The beauty of this proposed system is its autonomous and self-managed features. The system will have capability of including the following: laboratory activities; syllabi, homework and assignment; assessments (CBT- computer-based test), lecture notes; audio visual lectures; simulation; lesson plan; and textbooks etc. while the system will be own and maintained by Yaba college of technology Nigeria, it's services will be available for usage by any individual with interest in TVET across the globe.
