Description:BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to a safety device and particularly to a gas leakage detector device.
Description of Related Art
[002] Uncontrolled gas leakage poses a significant threat to human safety, property, and the environment. Flammable gases such as liquefied petroleum gas, methane, and butane create a high risk of fire and explosion when present in enclosed spaces. Toxic gases cause severe health hazards to humans and animals. Incidents of gas leakage in domestic and industrial environments have led to casualties, economic loss, and damage to infrastructure, highlighting the need for reliable detection and preventive measures.
[003] Moreover, conventional gas leakage management relies on manual monitoring or basic detectors that raise an alarm when gas concentration exceeds a threshold. Commercially available detectors connect detectors with ventilation devices or control panels in industrial settings. The commercially available detectors furthermore, typically employ semiconductor sensors, catalytic bead sensors, or infrared sensors for gas identification. These detectors serve as part of safety systems in kitchens, factories, warehouses, and other facilities.
[004] However, existing solutions suffer from limitations such as low sensitivity, false alarms due to environmental factors, delayed response, and lack of integration with automated safety mechanisms. Many detectors are restricted to audible or visual alerts without triggering preventive actions. Industrial systems that offer automation often involve high costs and complex installation, making them unsuitable for small-scale or domestic applications.
[005] There is thus a need for an improved and advanced gas leakage detector device that can administer the aforementioned limitations in a more efficient manner.
