Where should I place a carbon monoxide detector? | US EPA

· Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance. Keep the detector out of the way of pets and children. Each floor needs a separate ...

Where Should I Put My Carbon Monoxide Detectors? | Vivint

· The sensors in carbon monoxide alarms respond based on the concentration of CO in the air—the higher the concentration, the faster the alarm will respond. For low levels of carbon dioxide, it might take the alarm an hour to sense and respond. If levels are high, the alarm detects them in as little as four minutes. High levels of exposure can bring symptoms quickly, so it’s important to ...

Combustible Gas Safety Monitoring: Infrared vs. Catalytic ...

In IR point detectors, there is a fixed path length between the IR source and the IR detector (Fig. 3). The path length is typically short (a few inches) and the gas concentration is assumed uniform across the path. With a fixed path length, the measurement of IR beam absorption by the gas being measured can be expressed directly (% LELin this case). Thus, a

CO2 Sensor Location: Where to Mount Your CO2 IAQ Monitor ...

Indoor Air Quality: In most homes or offices, wall-mounted CO2 level transmitters are used to monitor carbon dioxide levels as they would be experienced by occupants. They can be located at the same height (48 inches or 122cm is standard) and on the same wall as you would mount a thermostat. Like a thermostat, they should not be near outside doors or windows that can make the space appear to …

Low Cost IR CO2 Sensors -

This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent performance to a conventional dual-channel CO2 sensor…

At What Height Should Sensors be Mounted?

The sensor mounting height depends the type of application and on the density of the gas relative to air. Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed in the "breathing zone" 4 - 6 feet from the floor. The breathing zone …

IR vs TC: Settling the CO2 sensor debate once and for all ...

· IR Sensors. IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a filter. Higher CO2 levels would cause fewer IR rays to pass through the filter and be detected by the sensor. Low CO2 levels would cause more IR …

How does an NDIR CO2 Sensor Work? |

The band of IR radiation produced by the lamp is very close to the absorption band of CO2. Because the IR spectrum of CO2 is unique, matching the light source wavelength serves as a signature or "fingerprint" to identify the CO2 molecule. As the IR light passes through the length of the tube, the CO2 gas molecules absorb the specific band of IR light while letting other wavelengths of light pass …
