Shelly Gas – CNG Gas Sensor WiFi

Shelly Gas is a smart CNG (natural gas) sensor designed for continuous monitoring of gas concentration in indoor environments. The device is plugged directly into a 110–230 V AC power outlet and connects to the home Wi-Fi network, allowing remote monitoring via a dedicated mobile application.

When hazardous gas levels are detected, the sensor triggers visual and audible alarms and sends notifications to the mobile app. Once gas concentration returns to a safe level, the device automatically resumes monitoring mode. The housing is made of fire-resistant materials to enhance operational safety.
