Carbon dioxide detectors

Carbon dioxide detectors (or CO₂ detectors) measure carbon dioxide, which is very unlikely to reach dangerous levels in any vehicle. High CO₂ levels could cause drowsiness, which is a risk especially when driving. Don't confuse carbon dioxide detectors with carbon monoxide (CO) detectors; be sure you're buying kind you want. Products listed here are battery powered; plug-in (AC) models are usually cheaper but not as well suited for nomadic living.
