1. A method for aggregating data, comprising:

  • receiving an alert from a low-power alert sensor, the alert specifies that an incoming sensor is detected by the low-power alert sensor to be joining a sensor array, wherein sensors in the sensor array comprise a plurality of different types of sensors;

    responsive to the alert from the low-power alert sensor, updating a record of capabilities of the sensors in the sensor array, the record of the capabilities of the sensors in the sensor array updated to reflect an addition of capabilities of the incoming sensor, the capabilities of the incoming sensor being described by the incoming sensor and specifying a sensing function performed by the incoming sensor;

    detecting a change in an environment based upon an output from the low-power alert sensor, the change detected while the sensors in the sensor array in the environment are in a power-conservation state;

    selecting a sensor in the sensor array to awaken from the power-conservation state based on;

    the change in the environment detected by the low-power alert sensor; and

    the record of the capabilities of the sensors in the sensor array;

    responsive to selecting the sensor, awakening the sensor in the sensor array;

    receiving sensor data about the environment from the sensor in the sensor array woken from the power-conservation state; and

    aggregating the sensor data into aggregated data.
