US Patent 11961381 Life safety device with machine learning based analytics

A detector is provided. The detector includes a sensor configured to detect airborne particulates at a premises and processing circuitry. The processing circuitry is configured to determine a characteristic associated with the detected airborne particulates, compare the characteristic associated with the detected airborne particles to data associated with predefined characteristics of burned materials, detect, based at least on the comparison, presence of a fire; and determine, if the presence of the fire is detected, a characteristic of the fire based on the characteristic associated with the detected airborne particles and the comparison.
