Abstract
An array of resonant sensors self-corrects measured values for the effects of environmental conditions, such as operating temperature, pressure or humidity. The resonant sensors have varied frequency responses to N environmental parameters and M chemical parameters. Each of the sensors has a different, non-zero frequency response to at least two of the parameters. The device also comprises at least one detector for detecting frequency responses of the resonant sensors. Individual parameter values are determined for each of the N environmental parameters and M chemical parameters according to the detected frequency responses and a system of equations using calibration terms that relate the frequency responses to the individual parameter values.
