How does the electric carbon monoxide detector in cabin or cockpit on aircraft work?
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.
