For example, in case of gas leakage or fire, power or electronic equipments running by power supply can increase chances of explosion. In an exemplary embodiment. In an exemplary embodiment, the relay (110) is an electrically operated switch, that allows current to pass through it or it is in on state when a high signal is provided to it or otherwise it is in off state. The relay can be used as a switch for the main power supply of the premises where the device can be installed. When there is no leakage high pulse can be provided to the relay and when there is gas leakage in the premises then a low signal can be provided to the relay that turns off the main power supply.

[0046] In an embodiment, the control unit (106) can be configured to receive voltage value from the converter (104), where the voltage value is associated with level of gas in the premises. The control unit (106) analyse the received value by comparing the value with a pre-defined dataset storing voltage value indicating level of gas harmful for human being. Upon detection of the level of gas above a pre-defined range by analysing the received voltage value, the control unit (106) can generate a first activation signal, a second activation signal, and a third activation signal. The first activation signal can be transmitted to the stepper motor (108), upon receiving the first activation signal, the stepper motor can rotate, and consequently, the gas supply valve can be closed to terminate leakage of the gas from the container of direct gas supply. For example, a regulator can be provided on the gas cylinder, the regulator valve can be rotated by the stepper motor to terminate gas leakage from the cylinder.
