1. A hazard detection system, comprising:

  • a housing;

    a wireless transceiver for receiving software updates;

    a system processor;

    a plurality of sensors comprising a smoke sensor, a carbon monoxide sensor, and a heat sensor; and

    a safety processor coupled to the system processor and the plurality of sensors and operative to;

    access a trigger band of at least one of the sensors;

    monitor the sensors for trigger events, wherein a trigger event occurs when a data value associated with a monitored sensor moves out of the trigger band associated with that monitored sensor, wherein the trigger band comprises a lower boundary and an upper boundary; and

    issue a signal to the system processor in response to each monitored trigger event; and

    wherein the system processor, responsive to the issued signal, is operative to;

    compute updated lower and upper boundaries of the trigger band based on at least one of the software updates and historical data obtained by at least one of the plurality of sensors;

    provide the updated lower and upper boundaries to the safety processor; and

    turn off the system processor such that the safety processor monitors for trigger events based on the updated lower and upper boundaries,wherein the system processor, the plurality of sensors, the wireless transceiver, and the safety processor are contained within the housing.
