Does it detect carbon monoxide?

No, it does not make any such claim. The description says, "When the chamber is filled with a certain density of smoke, it immediately raises an Alert". Smoke can be detected by a light sensitive device, because, it would obstruct the light falling on the sensor, but Carbon Monoxide is colourless and so, can not be detected by a light sensitive device.
