Smart home hazard detector that provides useful follow-up communication for detection events

摘要

The amount of ambient dangerous conditions may be monitored. The mode may be set to a state that indicates that a dangerous condition exists in the surrounding environment. Then, it may be determined that the amount of danger in the surrounding environment has dropped below a threshold dangerous state level. The amount of dangerous state in the environment surrounding the hazard detector may then be tracked for a period of time that remains below the threshold dangerous state level. It may be determined that the time period has at least reached the threshold duration, during which time the amount of dangerous condition in the environment surrounding the hazard detector is the threshold dangerous condition. Stay below the level. In response to the time period being at least a threshold duration, an indication that the dangerous condition is mitigating may be output.
