Description This product is designed to detect explosive gases (natural gas and LPG) in the air for homes, offices, and similar environments. In the event of a gas leak, it triggers an audible alarm with voice prompt, sends a notification to your mobile device via the app, and activates a connected valve or manipulator to shut off the gas source. Features: The gas leak detector is specifically designed to detect explosive gases such as natural gas (CH4) and LPG in residential and commercial spaces. Equipped with a large TFT color LCD screen that clearly displays date, day of the week, time, gas concentration level, and temperature. The display is easy to read even in low-light conditions. Supports 2.4 GHz Wi-Fi and is compatible with the Smart Life app, allowing remote monitoring and control via smartphone for added convenience. When a gas leak is detected, the device emits an audible alarm with voice alert, sends a push notification to your mobile app, and outputs a signal to close the gas valve or manipulator. Includes a built-in heat sensor that functions as a fire alarm by detecting rapid temperature increases caused by fire. Heat alarm triggers at 57°C.
