The answer to 'types of carbon monoxide detector' is that there are two main types of carbon monoxide (CO) detectors for homes: battery-powered and plug-in. Battery-powered CO detectors are portable and can be placed in different rooms, while plug-in detectors are hardwired into your home's electrical system. Both types use sensors to detect the presence of CO gas and sound an alarm to alert you to the danger.
CO detectors come in various designs, from small, discreet units to larger models with digital displays that show the current CO level. Some advanced detectors also have features like digital readouts, smart connectivity, and backup batteries to ensure they continue working even during a power outage.
