Immediate danger warning – dual warning system
It is worth taking care of safety today and equipping your house, flat or garage with a smoke detector. The device reacts instantly – in the event of danger, it activates a loud 85dB (decibel) audible alarm and a visual alarm in the form of a red LED. Thanks to the dual warning system, you can be sure that the alarm signal will reach all household members in time, even at night when the danger is particularly high.

Remote notifications via the Wi-Fi module and the Tuya or Smart Life app

Safety for children and the elderly
Carbon monoxide (CO) is particularly dangerous for children, the elderly and people with compromised immune systems, as even low concentrations can quickly lead to poisoning. By continuously monitoring the air, the sensor detects a hazard at an early stage and immediately triggers a loud 85 dB alarm and an LED indicator, warning household members of the danger. In addition, a notification in the mobile app allows you to react quickly and ensure the safety of your loved ones.
