This wiki has been updated 11 times since it was first published in December of 2018. A smoke alarm can alert you if there's a fire while you're at home, but when your loved ones and pets are there alone, you'll want to know right away if anything is wrong. These smart detectors will inform you of the presence of many harmful gases, like propane, carbon monoxide, and radon, while some use Wi-Fi to send notifications to a smartphone, so you can take care of the problem immediately. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.

Editor's Notes

January 13, 2021:

Depending on the type of gases you want to monitor, these smart detectors will give audible, visual, and smart device notifications, giving you time to take preventative action to eliminate the problem. Due to the nature of gas compounds, no one device is currently able to detect all harmful gasses, therefore we selected a range of devices to cover most needs.

For flammable or explosive gasses, the Cazoner 360 Degree Luminous, the i.Valux Sensor and the Yu-Niyut Tuya are the best choices, with the latter alerting users via push notifications in conjunction with a downloadable app. For monitoring carbon monoxide, which is usually present if there is a fire, the Kidde Nighthawk is a good choice that also detects explosive gas levels and updates every 15 seconds. The Radon Eye RD200 and the Airthings 4200 House Kit are both designed primarily to detect naturally occurring radon levels, with the latter also measuring air quality and chemical impurities. Finally, the uHoo 9 In 1 uses an intuitive app that displays several metrics on the quality of air in your home, including carbon dioxide and nitrogen dioxide.

The top items on our list are those that not only can monitor for several harmful substances, but those that can be easily installed and integrated. Though there are many carbon monoxide detectors that can be integrated with smart home systems, you'll need to check the compatibility and know how to set them up. The best choices can be easily connected to a smartphone so you can use them without a lot of hassle.
