Patent ID: 10436748

Abstract:
This disclosure describes methods, apparatuses, and systems to determine the presence of a chemical substance in an environment, by detecting one or more chemical substances in the environment by using at least one sensor that performs one or more electrochemical tests on one or more chemical samples in the environment, and generates one or more electrical signals corresponding to the chemical samples in the environment. The methods, apparatuses, and systems may also receive and process the one or more electrical signals corresponding to the one or more samples from the environment, wherein the methods, apparatuses, and systems compare the electrical signals to electrical signals corresponding to profiles of known chemical substances in the environment to determine if a match exists. The methods, apparatuses, and systems may compare the electrical signals to baseline threshold values of known chemical substances in the environment to determine if there is an excess or lack of the chemical substance. The methods, apparatuses, and systems may compare the electrical signals to both the stored profiles and baseline threshold values of known chemical substances in the environment to determine if known chemical substances are present in the environment. The methods, apparatuses, and systems may display an alert to confirm, deny, or require further testing to confirm or deny the presence of known chemical substances.
