A chemical detection sensor system comprises a support structure; multiple SERS chemical detection sensors supported by the support structure; multiple chemical reaction sensors, wherein each of the chemical reaction sensors is disposed for undergoing a state change in response to an occurrence of a chemical reaction at one of the SERS chemical detection sensors; a processor supported by the support structure for recording data representing occurrence of a chemical reaction at any of the chemical detection sensors in response to sensing the state change; and a power source for energizing the processor.
