Safety first

Push notifications

Increase your sense of security with Tellur’s WiFi Smart Gas Sensor. Having an unique air flow design, the core sensor is protected from vapors, oil spills or smoke, ensuring its continuous operation. When it detects gas, the sensor alerts you through an acoustic alarm, a light indicator and a push notification is sent to your smartphone.

Low Energy Consumption

The sensor integrates perfectly in the Smart Home ecosystem and allows you to check its working status and history records by simply accessing the Tellur Smart app from your smartphone. Also from the app you can remotely mute the alarm or make the sensor to perform a self-check just to be sure the device is operating effectively.
