The Aqara Smart Gas Detector (JT-BZ-03AQ/A) is a dedicated safety device designed to monitor your home for methane leaks. It connects via the Zigbee wireless protocol, allowing it to integrate into a smart home ecosystem to alert you immediately if gas is detected. Housed in a compact white casing measuring 80.4 x 31 mm, the sensor produces an 85 dB alarm to ensure you hear the warning even from another room. It operates on a 12V power supply and is built to function reliably in temperatures ranging from -10°C to 55°C and humidity levels up to 93%. For installation, the package includes both a mounting plate with screws and expansion tubes for a permanent fix, as well as an adhesive sticker for more flexible placement. This makes it a practical choice for homeowners who want a constant, automated watch over their kitchen or utility areas.
