The Shelly Gas monitors rooms for gas leaks. In case of danger, the sensor starts to whistle and blink, sending an alarm notification to the Shelly app. It can optionally be connected to the Shelly Cloud. Many household appliances rely on natural gas, but they rarely have built-in gas leak detection. The Shelly Gas is a natural gas sensor that can provide additional protection for your home and family. Thanks to its long lifespan and Wi-Fi technology, you will always know if gas poses a threat to your home. The gas sensor can also directly control a Shelly switch actuator, allowing it to close an electric gas valve, for example.
