Smart-home hazard detector providing useful follow up communications to detection events
First Claim
1. A method for detecting that a hazardous condition is easing, the method comprising:
- measuring, by a hazard detector, a first amount of the hazardous condition present in an ambient environment of the hazard detector;
setting, by the hazard detector, a mode of the hazard detector to a state indicative of the hazardous condition being present in the ambient environment of the hazard detector;
measuring, by the hazard detector, a second amount of the hazardous condition present in the ambient environment of the hazard detector, the second amount of the hazardous condition being less than the first amount of the hazardous condition;
determining, by the hazard detector, that the second amount of the hazardous condition present in the ambient environment of the hazard detector is below a threshold hazardous condition level while the mode of the hazard detector is set to the state indicative of the hazardous condition being present;
tracking, by the hazard detector, a time period during which the amount of the hazardous condition present in the ambient environment of the hazard detector has remained below the threshold hazardous condition level while the mode of the hazard detector is set to the state indicative of the hazardous condition being present;
determining, by the hazard detector, that the time period has reached at least a threshold duration, during such time period the amount of the hazardous condition present in the ambient environment of the hazard detector having remained below the threshold hazardous condition level while the mode of the hazard detector is set to the state indicative of the hazardous condition being present; and
outputting, by the hazard detector, an indication of the hazardous condition easing in response to the time period being at least the threshold duration.

Abstract
Ambient amount of a hazardous condition may be monitored. A mode may be set to a state indicative of the hazardous condition being present in the ambient environment. It may then be determined that the amount of the hazard in the ambient environment has dropped below a threshold hazardous condition level. A time period may then be tracked during which the amount of the hazardous condition present in the ambient environment of the hazard detector has remained below the threshold hazardous condition level. It may be determined that the time period has reached at least a threshold duration, during such time period the amount of the hazardous condition present in the ambient environment of the hazard detector having remained below the threshold hazardous condition level. An indication of the hazardous condition easing may be output in response to the time period being at least the threshold duration.
