Why Standard Smoke Detectors Leave Your Family Vulnerable
Your standard smoke detector only checks for smoke. It is completely blind to gas leaks and carbon monoxide—a deadly, invisible gas with no smell, no color, and no warning signs. Traditional CO alarms stay silent until levels reach a dangerous 70 PPM, and safety standards allow them up to 4 hours to trigger at that level. By then, your family has been breathing poison for hours.
SentinelGuard™ replaces outdated alarms with total home security. It continuously monitors your air 24/7 for smoke, gas leaks, and carbon monoxide in a single unit. Instead of waiting for danger to peak, it shows live CO readings starting from 0 PPM and alarms at 50 PPM—giving you crucial time to act before it's too late.
Key Features & Benefits
3-in-1 Multi-Hazard Protection: Combines electrochemical and photoelectric sensors to detect smoke, natural gas leaks, and carbon monoxide in one compact device.
Real-Time Digital Display (From 0 PPM): No more guessing if your sensor is working. The clear color screen displays real-time CO numbers, room temperature, and humidity. If the numbers change with your environment, you know it’s actively protecting you.
12-Hour Backup Battery: Plugs into any standard outlet and charges automatically. If the power drops, a breaker trips, or you unplug it, the internal battery keeps watching for 12 hours.
Zero False Alarms: Industrial-grade selective sensors specifically target hazards without triggering from everyday cooking steam, shower humidity, or aerosol sprays.
Plug-and-Play & Ultra-Portable: No wiring or apps required. Plug it into the wall or swap to the included magnet mount to stick it on your fridge. Perfect for home, Airbnb, hotels, dorms, and RVs.
Loud Alarm & Soft Nightlight Mode: Designed to wake you from a deep sleep with adjustable volume. Features a night mode that dims the display into a soft nightlight for hallways or kids' rooms.
How Many Do You Need?
Single Unit: Essential for the primary bedroom (carbon monoxide is most dangerous while you sleep).
2-Pack (Most Popular): One near the bedrooms and one in the kitchen/living area near stoves, furnaces, or water heaters.
3-Pack (Best Value): Complete coverage for bedroom, kitchen, and garage or basement.
Placement Tip: Mount 4–5 feet high on the wall for optimal CO detection. Avoid placing directly across from high-heat stove burners, air vents, or behind curtains.

At one glance I can read the CO2 PPM, the temp and the humidity. We have frequent power outages here in CA due to PG&E so my li battery takes over automatically.
I am using it in my house until I take out the RV then I will use it in the RV. Versatile and useful!
Bought the 2-pack: one for the motorhome and the other for our cabin in the woods as we are on LP there (see pic). Plug n play, clear info display makes it easy to understand. These sensors give us much peace of mind. Highly recommended.
I love my 6 in 1 CO Detector. It looks very high tech but it is very simple to use. With my gas grill off, I place the CO detector inside the grill and turned on the propane. Within seconds the alarm sounded.
The temperature displayed on the unit matches the thermostat in my home exactly and I like that the display can be rotated.
Very easy to use and very clear readings! Really like this to monitor and alert any issues!
Really piece of mind for our RV, one in the bedroom and one up by the kitchen. Clear, easy to read display. Would highly recommend it.
My factory detector still works fine, but it always bugged me that I had no idea what the actual level was. The UL standard doesn't make these alarms go off until 70 PPM, and from what I read your body's already taking a hit above 50. So you could be sitting in something harmful and have no clue. That's what got me, the not knowing. Now I can just look at the screen and see exactly where things are at. Sleep a lot easier knowing that.
The screen is bright and easy to read, so I can check CO and gas levels at a glance and it really gives us peace of mind out on the road. I love that it combines several sensors into one unit, which keeps things simple in a small RV space. It also feels solid and well-built, which matters a lot when you're sleeping in a camper with a propane stove and a generator running nearby.
Just unboxed this thing. Feels really solid and looks way more high-tech than the old detector in our motorhome. Can't wait to get it plugged in for our next trip.
I like these detectors. No worries about dead batteries and it detects multiple things. Very nice.
Fast shipping. Tested it out per the manual and the response time is incredibly quick. Putting it in the rig tomorrow.
works great, love the battery backup
Took a little longer than I wished to arrive but I’m thrilled now that they are here and working perfectly. So comforting to get real feed back and not just an idiot light. I installed both in my 40’ motorhome. One upfront in kitchen living area and one in the rear bedroom.
Tested it at home can’t wait to replace my hard wired rv unit
So far, very pleased with the easy set up and location. Easy functions to read.
