Carbon Monoxide Detector

The carbon monoxide detector is a smart safety device that provides 24/7 real-time monitoring of indoor carbon monoxide (CO) levels. Once CO concentration reaches a dangerous threshold, the device instantly triggers an 85dB sound and light alarm and sends remote notifications via a smartphone app, ensuring you’re informed no matter where you are. With direct Wi-Fi connectivity and no hub required, it’s easy to install and operates on battery power—no wiring needed. Ideal for homes, RVs, and a variety of indoor environments.
