You may think carbon monoxide detectors for car monoxide detectors are a good idea to have at home where gas leaks or other causes of poisoning can occur, but your car is not immune to the dangers of this invisible gas. A CO detector for your vehicle can help you avoid the dangerous exposure to carbon monoxide by warning you if high levels are detected. Typically, these detectors will sound an alarm at 300 parts per million or higher. The best car carbon monoxide detector should be easy to install and small enough not to obstruct your driving view. Some models also have added features such as digital displays or smartphone connectivity that can enhance your safety and convenience.

On the Road to Safety: Protecting Yourself with Car Carbon Monoxide Detectors

Unlike smoke detectors that use heat or flame to detect a fire, carbon monoxide detection works using electrochemical and metal oxide sensors. When carbon monoxide enters the gas-permeable compartment that houses the sensor, it lowers the sensor’s resistance and triggers a surge in current passing through it. The specific amount by which the current surges tells the detector the concentration of carbon monoxide molecules. Those with metal oxide sensors employ the same principle, but instead of using a chemical solution, they use a metal oxide chip.

The FASOHERE car carbon monoxide detector doubles as a fast dual USB car charger and offers a variety of other useful features for your peace of mind on the road. It has a blue backlit LED display that makes it easy to read CO readings, and a test button that lets you know the device is working properly. It also has a peak memory feature that records readings, and two backup AA batteries are included.
