Multimodal analyte sensor network

A system for detecting an analyte in a detection region, the system comprising:

• an analyte sensor network in the detection region comprising a sensor node array having a plurality of nodes and a local gateway;
• wherein the plurality of nodes comprise at least one first node and a plurality of second nodes distributed throughout the detection region,
• wherein the at least one first node comprises a first analyte sensor;
• wherein each node of the plurality of second nodes comprises a second analyte sensor;
• wherein the first analyte sensor has a lower detection limit than the second analyte sensor;
• one or more computer processors;
• one or more computer-readable storage media;
• program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising instructions to:
• operate in a first mode comprising instructions to:
• detect the analyte with the analyte sensor network established within the detection region,
• wherein the instructions to detect the analyte comprise instructions to identify an electrical signal generated by an electrochemical reaction of the analyte with the first analyte sensor or the second analyte sensor;
• in response to the electrical signal exceeding a first threshold value, operate in a second mode comprising instructions to:
• request, based on the electrical signal exceeding a first threshold value, data associated with one or more environmental conditions of the detection region;
• determine an analyte concentration based on the one or more environmental conditions;
• and
• transmit, by the local gateway, data associated with the analyte concentration in response to the analyte concentration exceeding a second threshold value.
