Which environmental factor can affect the performance of smoke detectors?

The performance of smoke detectors can be influenced by a variety of environmental factors, including room temperature, humidity levels, and airflow.

Room temperature is critical because smoke detectors are designed to operate within certain temperature ranges. Extreme heat or cold can affect their sensitivity and response time.

Humidity levels play a significant role as well. High humidity can cause condensation inside the detector, which can lead to false alarms or reduced effectiveness in detecting smoke particles. Conversely, very low humidity may decrease the ability of the detector to accurately sense smoke due to the absence of moisture in the air.

Airflow affects the distribution of smoke particles around the detector. Heavy airflow can disperse smoke before it reaches the sensor, potentially delaying or preventing the alarm from activating in the presence of a fire.

Considering that each of these factors—room temperature, humidity levels, and airflow—can materially impact the functionality of smoke detectors, it is accurate to conclude that all of these environmental factors collectively have a significant effect on their performance.
