Key Takeaways:

  • Carbon monoxide (CO) poisoning is a serious threat in RVs due to the potential buildup of CO gas from generators, which can occur in poorly ventilated spaces.
  • Investing in a carbon monoxide detector for your RV is essential to protect your family’s safety on the road.
  • Carbon monoxide detectors are designed to detect CO gas in enclosed spaces using reliable sensors such as MOS and Pellet Sensors.
  • When choosing a carbon monoxide detector for your RV, consider factors such as reliable sensors, size, easy-to-read display, loud alarm, long battery life, and low battery indicator.
  • Top recommendations for RV carbon monoxide detectors include models like the Honeywell Wireless CO Detector (5800), ALERT PRO Carbon Dioxide Detector, Google Nest Protect, and WolfShield Carbon Monoxide Detector.

Ensuring the safety of your family while on the road is important, and one way to do this is by investing in a carbon monoxide detector for your RV. While parked, RVs can produce deadly carbon monoxide gas from their generators, and this gas can quickly build up to dangerous levels inside the RV if there is poor ventilation.

Carbon monoxide is an odorless, colorless gas. Don’t let its invisibility fool you-it’s deadly. The gas can cause headaches, dizziness, nausea, and even death. For RVers, it’s especially important to have a carbon monoxide detector because RVs are often parked in close proximity to other vehicles, and the gas can easily build up. In fact, carbon dioxide poisoning occurs more often in RVs than in any other type of vehicle.

What is a Carbon Monoxide Detector?

A carbon monoxide detector for RV is an important safety device that can help protect you and your family from the dangers of carbon monoxide poisoning. Carbon monoxide poisoning can occur when there is a buildup of the gas in an enclosed space. Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, and vomiting. In severe cases, it can cause coma and death.

Aside from its deadly effects, carbon monoxide is also difficult to detect because it is odorless and colorless. This makes it hard to know when there is a problem until it’s too late. This is why having a carbon monoxide detector in your RV is so important.

How Does a Carbon Monoxide Detector Work?

Since carbon dioxide can’t be easily detected by a human’s nose, a carbon monoxide detector is equipped with a sensor that can detect the presence of the gas. They are designed to monitor the air for the presence of carbon monoxide gas. This gas is produced whenever fuel is burned, so it’s present in RV engines and any other combustion engines.

This lifesaver will sound an alarm if the level of gas in the air reaches a certain level. This level is based on the amount of time it would take for symptoms of carbon dioxide poisoning to appear. Initially, carbon monoxide detectors were initially used in industrial settings, but they are now common in homes and RVs.

There are two types of sensors that are used in carbon monoxide detectors:

MOS (Metal Oxide Semiconductor) Sensor:

This type of sensor uses a chip that is coated with a metal oxide. The chip produces an electric current when it comes into contact with carbon monoxide molecules. The current is then converted into a reading that is displayed on the detector.

Pellet Sensors:

This type of sensor uses a pellet that changes color when it comes into contact with carbon monoxide. The change in color is then used to determine the level of gas in the air. Often, these sensors are used in combination with MOS sensors.

What to Look for in a Good RV Carbon Monoxide Detector

Checking your tires, or getting your RV for a preventive maintenance checkup is important to make sure your RV is in top running condition. But this doesn’t stop here. Getting equipped with the right safety devices is just as important. Here are some things to look for when choosing a carbon monoxide detector for your RV:

Reliable Sensors

There are a few things you’ll want to keep in mind when shopping for a carbon monoxide detector. First and foremost, you’ll want to make sure that the device has reliable sensors. Carbon monoxide is an invisible gas, so it’s important to have a detector that can accurately detect its presence. We can’t deny the fact that there have been some cases where carbon monoxide detectors have given false alarms. But this doesn’t mean that you should avoid them altogether. Just be sure to choose a reliable brand and model.


When it comes to safety devices, size doesn’t always matter. But in the case of carbon monoxide detectors, it’s important to choose one that is the right size for your RV. While most of these devices won’t take up much of your RV’s space, some are larger than others. If you have a small RV, you might want to choose a smaller carbon monoxide detector.

Easy-to-Read Display

Another important feature to look for in a good carbon monoxide detector is an easy-to-read display. The display should be large and backlit so that you can easily see it, even in low-light conditions. Additionally, the display should show the current carbon monoxide level as well as the peak level over a period of time. This information will help you determine if there is a problem and how severe it is.

Loud Alarm

Getting alerted of a carbon monoxide leak is important, but it won’t do you any good if you can’t hear the alarm. That’s why it’s important to choose a carbon monoxide detector with a loud alarm. The alarm should be loud enough to wake you up if you’re asleep, or get your attention if you’re in another part of the RV. Ideally, the alarm should be at least 85 decibels.

Long Battery Life

There are two types of carbon monoxide detectors – those that run on batteries and those that plug into an outlet. If you choose a battery-powered detector, be sure to choose one with long battery life. RVs can be unpredictable places, so you never know when you might lose power. That’s why it’s important to choose a carbon monoxide detector with long battery life. Many of these devices come with batteries that will last for at least 5 years.

Low Battery Indicator

Before heading out on your next RV trip, be sure to check the batteries in your carbon monoxide detector. This is especially important if you choose a battery-powered detector. Many of these devices come with a low battery indicator, which will let you know when it’s time to replace the batteries. It’s worth noting that these detectors will still work even if the batteries are low. However, they might not be as accurate.

Our Top 4 Recommendations for RV Carbon Dioxide Detectors

Part of living the RV lifestyle includes using appliances and devices that use propane. While propane is a very safe fuel, there is always the potential for a leak. This is one of the plausible sources of carbon dioxide in your RV. To help you keep your family safe, we’ve compiled a list of our top four recommendations for RV carbon dioxide detectors.

    I bought First Alert to replace the CO alarm in the RV. I was researching the model I had and didn’t want to pay more than $70 for it so I researched alternatives and this model popped up on RV forums to buy. It’s smaller than we had, but I prefer the smaller size better. It came with the battery already installed, so all I had to do was try to pull the protective plastic tab and it worked right away. I press the test button and everything seems to be working fine. I will be
    and will use this as a backup from now on. I’m glad Amazon carries these at an honest price.
