What Does a Carbon Monoxide Detector Do and How Does it Work?

· The CO alarm sounds if your sensor detects a buildup of carbon monoxide in your home—usually before you start sensing symptoms. With a low CO level (50 ppm), it may take up to eight hours for the alarm to go off. Higher levels (over 150 ppm) can trigger an alarm within minutes. 3. Act quickly when an alarm sounds because low doses over long periods can be just as dangerous as …

Why CO2 sensors alone are not enough

Why CO2 sensors alone are not enough. When people share a room, the amount of exhaled carbon dioxide (CO2) usually increases sharply. But performance is not solely dependent on the CO2 content; other factors also play a role. What are CO2 sensors? Wellbeing, performance, and motivation are closely related to the CO2 concentration in the room air. CO2 is a tasteless and odorless gas that ...
