Carbon Monoxide Alarm Beeping? Here's What to Do.

When CO is detected, the carbon monoxide alarm’s sensor triggers an alarm to alert you. If you’re unsure if the alarm is working, test it by checking the wall outlet’s power or batteries. Why is my carbon monoxide detector beeping every 30 seconds? Carbon monoxide detector beeping intermittently can signal different alerts. Check your detector’s manual. If your alarm sounds every 30 ...

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR ...
