Story summary

Smoke alarms may chirp at night when cooler temperatures affect battery performance, disrupting sleep.
During the day, higher temperatures reduce electrical resistance, allowing batteries to function normally.
Low battery warnings are more common at night, especially between 2 a.m. and 6 a.m.
Older smoke detectors are more prone to false alarms due to dust accumulation and degraded sensors.
To prevent nighttime chirping, replace batteries regularly and consider upgrading to smart alarms.
