The Tellur smart WiFi smoke and carbon monoxide sensor is designed to protect you from two main threats - smoke and carbon monoxide (CO). The sensor gives you instant real-time alerts if smoke or carbon monoxide is detected, allowing you to react quickly and save lives. With an alarm volume of 85 decibels, you can hear it from a distance,which ensures that you will know when the sensor detects a potential danger. The sensor is simple to install and use. It includes a large button for alarm testing and suppression, automatic calibration, low battery warning, and is integrated into the Tellur Smart app that allows you to monitor the sensor's status and receive notifications directly to your device. It is compatible with voice assistants, which increases its user-friendliness and flexibility.
