【ZX-GS21】
Wifi Gas Detector

This GS21 gas detector connects to Tuya WiFi network for 24h remote monitoring on your phone. Once gas leakage or overheat is detected, the system sends instant text push alerts to your mobile anywhere. The APP synchronously shows real-time gas %LEL value and ambient temperature data. You can check historical detection records remotely, get fault reminders and sensor lifespan prompts via the smart APP, realizing unattended home safety monitoring without distance limits for families and commercial venues.

Built-in full-view LCD screen shows all key data intuitively at a glance: real-time combustible gas concentration (%LEL), surrounding temperature, clock, calendar date, and remaining sensor service days. When faults occur, the screen will display fault codes for quick troubleshooting. Different alarm states correspond to matched flame and temperature icons, enabling users to judge hidden dangers without opening the APP, combining clock decoration and safety detection in one circular device for home kitchen layout.

Dual safety detection modes greatly reduce fire and explosion hazards. For gas leakage, it triggers sound-light alarm when gas concentration hits 6%LEL, sensing natural gas, methane and LPG efficiently. The heat alarm activates when ambient temperature reaches 57°C to warn of abnormal high temperature risks. Local buzzer sound + flashing red indicator work simultaneously, forming double safety barriers to respond to two major kitchen hidden dangers: gas leakage and overheating.

Adopts high-sensitivity diffusion-type gas sensor with fast 30-second response time, accurate detection within ±3%LEL tolerance. The built-in chip tracks sensor usage days and reminds users to replace the sensor in advance via screen and APP alerts when service life expires (5-year standard lifespan). Automatic self-check function identifies sensor failures and lights yellow fault indicator timely, avoiding invalid detection caused by aging sensors and ensuring long-term stable safety monitoring.

Powered by Micro USB 5V safe low voltage, compatible with all standard USB adapters. Simple wall-mounted installation with clear position guidelines, suitable for kitchen, hotel, office building, school, warehouse and catering venues. Compact round minimalist appearance fits various indoor decoration styles. It supports independent local alarm without WiFi connection, while WiFi function adds remote smart linkage, meeting both household and commercial public space safety supervision demands.
