Options are:\n\n**0 ppm:** this will assume no CO in the air
\n**Low level:** this will assume a level between 1 and 35 ppm, inclusive. This level is generally assumed to not cause problems in healthy adults
\n**Dangerous level:** this will assume a level between 35 and 5000, inclusive; this will also trigger an alert in Home app\n\n## IF YOU HAVE A CARBON MONOXIDE DETECTOR EVER READING ABOVE 35 PPM, PLEASE EVACUATE THE AREA AND SEEK FRESH AIR IMMEDIATELY TO AVOID RISK OF DEATH ##\n\n# CO2 Sensor\n\nThere are three inputs to this example, one for each level of Carbon Dioxide in the air. Options are:\n\n**0 ppm:** this will assume no CO2 in the air
\n**CO2 Level:** this will assume a level between 1 and 100,000 ppm, inclusive
\n**Dangerous level:** this will assume a level between 1,000 and 100,000, inclusive\n\n"
