A method of detecting and providing notification of carbon monoxide in a house or building structure, comprising:
- establishing, at a device, an alarm condition based at least in part on a predetermined amount of carbon monoxide in a house or building structure;
- establishing, at the device, a pre-alarm condition based at least in part on a predetermined trend in the amount of carbon monoxide in the house or building structure;
- receiving, at the device, signals from one or more sensors, the signals being indicative of the amount of carbon monoxide in the house or building structure;
- analyzing, at the device, the signals to detect at least one of the alarm condition or the pre-alarm condition;
- responsive to detecting the alarm condition, providing a notification of the alarm condition;
- and
- responsive to detecting the pre-alarm condition but not the alarm condition, providing a notification of the pre-alarm condition,
- wherein the predetermined trend is a steady increase in the amount of carbon monoxide over a period of at least one day.
