Yes, humidity can affect the smoke detector and cause false alarms. High humidity, especially in areas such as bathrooms or kitchens, can cause moisture to accumulate inside the detector, which is then misunderstood by the sensor as smoke.
Here is a detailed analysis done by anka security for you:
Humidity and sensors:
Smoke detectors, especially photodetectors, are sensitive to moisture. When the humid air cools down, it condenses into water droplets, which then attach to the sensor of the detector.
Confusing sensor:
The detector's sensors may mistake these droplets or moisture for smoke particles, causing false alarms.
False alarm:
This can lead to frequent false alarms, especially in areas with high humidity or steam-generating areas such as bathrooms, kitchens or laundry rooms.
High humidity area:
High humidity areas such as coastal areas are more likely to encounter these problems.
Prevent false alarms:
To alleviate this, make sure that the high humidity areas are well ventilated, consider using a dehumidifier, and make sure your smoke detector is not installed near steam or moisture sources.
