3 Ways to Test a Carbon Monoxide Detector - wikiHow

· Having a carbon monoxide (CO) detector in your home can help protect you from carbon monoxide poisoning, but only if it works properly. Checking your detector regularly will help make sure your family is safe. You should test the sensor on the unit annually with a special tester spray, and check the alarm circuitry once a month by pressing the test button.

How Carbon Monoxide Detectors Work | HowStuffWorks

­CO detectors can use several types of sensors to sense carbon monoxide in the air. Biomimetic sensor technology reproduces CO's effects on hemoglobin in the blood. In a biomimetic sensor, a gel changes color as it absorbs CO. A separate sensor detects the c­olor change and alerts the detector's processor to sound the alarm.
