Abstract
A chemical-detecting apparatus includes an array of sensors. Each sensor of the array of sensors is oriented skyward in operation. Each sensor includes a chemical receiver including a plurality of infrared color vision filters cooperating to detect a plurality of infrared color vision signatures. The plurality of infrared color vision signatures respectively correspond to a plurality of chemicals. Each sensor includes a transmitter configured to transmit a detected chemical identifier, based on a detected infrared color vision signature of the plurality of infrared color vision signatures and corresponding to a detected chemical of the plurality of chemicals, to at least one neighboring sensor of the array of sensors. The transmitter is configured to transmit a detected chemical confirmation from the neighboring sensor to a first-identifying sensor of the array of sensors and is configured to transmit a confirmed chemical alarm, based on the detected chemical confirmation, from the first-identifying sensor.
