The widespread availability of smoke alarm controllers tell us one thing: smoke alarms are going off more often than people would like. As opposed to being installed into an existing smoke alarm, the Nest Protect Smoke & Carbon Monoxide Alarm is a wholesome device, which also explains the steep price.

It probably won’t go well with your interior design, but its smoke detection options are worth consideration

Its standalone utility means that you’ll have to figure out where to place the gadget, but it also means that you’ll enjoy greater versatility in terms of smoke detection. Working on its own also makes this an ideal purchase for homes without an existing smoke alarm system, although larger homes will probably need several of these devices to ensure timely smoke detection.

Aside from full control through an app, the Nest Protect Monoxide Alarm’s most attractive feature might be its carbon monoxide detection. As opposed to just dealing with smoke of the burning variety, this sensor will let you know whether carbon monoxide has been building up in your home, and its portable properties will make detecting the source of the leak easy.

As you’ll probably notice, the Nest Protect Smoke & Carbon Monoxide Alarm price of $120 on Amazon makes it a greater expense than similar devices, but the features make up for it. Since it doesn’t use batteries, you won’t need to worry about having to replace them, making this a decent purchase for those looking for a manageable smoke sensor that’s also able to alert you of carbon monoxide, even in smaller amounts.
