Kidde Smart CO Detector & Indoor Air Quality Monitor | Plug-In, WiFi, Alexa Compatible

Meet the Kidde Smart Carbon Monoxide Detector & Indoor Air Quality Monitor, a plug-in device that merges CO detection with IAQ sensing in one compact unit. It uses an electrochemical sensor to identify CO gas and, when danger is detected, triggers an 85-decibel alarm paired with a clear voice alert to name the hazard.

The unit plugs into a standard 120V wall outlet and features a lithium battery backup that lasts the full 10-year life of the alarm, so you can rely on continuous coverage even during a power outage. A crisp digital display provides real-time readings of CO levels and IAQ metrics, while the accompanying app keeps you in the loop wherever you are. If you are away from home, you can still receive alerts on your phone, and compatible smart speakers let you check status with your voice.

Getting set up is simple: download the Kidde app, scan the QR code on the back of the alarm, and plug it in. The device can be paired with Amazon Alexa, Google Home, and select iPhone and Android devices, enabling voice checks and hands-free status updates.

What you’ll notice in daily life

In addition to carbon monoxide, the device keeps an eye on Total Volatile Organic Compounds TVOCs emitted by cleaners, paints, and building materials, as well as humidity. These readings can help you understand room conditions and detect changes that might affect comfort or mold risk. The digital display shows live data, while the Peak Level Memory button records the highest CO level reached since last reset, giving you a quick reference for trends.
