The Gas Leakage Sensor serves as a critical safety device, suitable for installation in various gas-related appliances like gas stoves and mechanical rooms. Its primary function is to continuously monitor for the presence of gas leaks, including natural gas (CH4). In the event of a gas leak, this sensor is equipped to emit a loud alarm, promptly alerting individuals in the vicinity. For example, if installed in a home and a gas leak is detected while occupants are asleep, it can swiftly awaken them, raising awareness of the potential danger. Additionally, it can send alerts to mobile devices, ensuring that you are notified even when you are away from home. Furthermore, you have the option to configure scenarios where, upon detecting a leak, the sensor will automatically shut off the main gas valve and cut off the house's power supply. This enhances safety measures and helps mitigate further risks.
