Carbon monoxide detector - Wikipedia

This sensing element must be heated to approximately 400 °C for operation. Oxygen increases resistance of the tin dioxide while carbon monoxide reduces resistance. The integrated circuit monitors the resistance of the sensing element. Lifespans are approximately five years and alarms need testing on installation and at least annually with a test gas. The large power demand of this sensor ...
