The present invention involves a multimodal sensor network for analyte detection. A first mode may involve low-power detection and a second mode may involve determining an analyte concentration and transmitting data associated with the analyte concentration. Specifically, the first mode may include establishing an analyte sensor network in a detection region, detecting an analyte in the detection region, and generating an electrical signal in response to the detecting the analyte. In response to the electrical signal exceeding a first threshold, the analyte detection system may operate in the second mode. The second mode may include requesting data associated with the one or more environmental conditions, determining an analyte concentration based on one or more environmental conditions transmitting data associated with the analyte concentration.
