Onelink by First Alert Environment Monitor helps you ensure a healthy and comfortable environment in your bedrooms or any other part of your house by constantly monitoring air quality, temperature, and humidity with the app on your smartphone.

Once in place, it quickly starts identifying and alerting you to low-level carbon monoxide (CO), which is especially harmful to infants. If it detects extremely dangerous levels of CO the monitor sounds a loud siren. The illuminating LED ring on the monitor will change colour, indicating shifts in temperature.
