Passive bioinspired sensor

An apparatus comprising:

• an array of sensors, each sensor of said array of sensors being oriented skyward in operation,
• wherein said each sensor comprises:
• a chemical receiver comprising a plurality of infrared color vision filters cooperating to detect a plurality of infrared color vision signatures, said plurality of infrared color vision signatures respectively corresponding to a plurality of chemicals, said chemical receiver comprising an ambient reference chemical filter, said ambient reference chemical filter generating an ambient reference concentration level, and
• a transmitter configured to transmit:
• a detected chemical identifier, based on a detected infrared color vision signature of said plurality of infrared color vision signatures and corresponding to a detected chemical of the plurality of chemicals, to at least one neighboring sensor of said array of sensors,
• a detected chemical confirmation from said neighboring sensor to a first-identifying sensor of said array of sensors, and
• a confirmed chemical alarm, based on the detected chemical confirmation, from said first-identifying sensor,
• wherein said chemical receiver comprises a detection chip communicating with said plurality of infrared color vision filters and said ambient reference chemical filter,
• wherein said plurality of infrared color vision filters is configured to produce a detected chemical signature from the detected infrared color vision signature,
• wherein said detection chip is configured to generate a comparative concentration reading based on the detected chemical intensity and the ambient reference concentration level.
