$\begingroup$ You may find the Wikipedia article on Carbon monoxide detector informative. That article mostly talks about home detectors, but the technology is the same. $\endgroup$– Greg HewgillCommented Sep 14, 2017 at 3:27

There are three major types of carbon monoxide senors.
- Biomimetic: A gel changes color when it absorbs carbon monoxide.
- Metal oxide semiconductor: When the chip's circuit detects carbon monoxide, electrical resistance decreases, and this triggers an alarm.
- Electrochemical: Electrodes immersed in a chemical solution sense changes in current when they come into contact with carbon monoxide, and this change triggers the alarm.
