Abstract

A system for measuring parameters in a container is disclosed. A system for measuring multiple parameters includes a container having a solution, at least one sensor in conjunction with a tag is in proximity to an impedance analyzer and a reader that constitute a measurement device. The at least one sensor is configured to determine at least one parameter of the solution. The tag is configured to provide a digital ID associated with the sensor, where the container is in proximity to the reader and an impedance analyzer. The impedance analyzer is configured to send and receive a given range of frequencies from the sensor, based on the parameter and calculate parameter changes based on the response.

Claims

1. A method for measuring multiple environmental parameters, comprising:

obtaining a given range of frequencies from at least one sensor based on at least two environmental parameters;

calculating changes of the at least two parameters by using multivariate analysis on the real and imaginary parts of the complex impedance measured by an impedance analyzer as a function of the received frequencies sensor;

applying multivariate analysis to the data collected; and

quantifying the at least two environmental parameters of interest.

2. The method for measuring multiple parameters of claim 1, wherein the at least one sensor is in conjunction with a tag and the method further comprises the step of:

obtaining a digital ID from the tag.

3. The method for measuring multiple environmental parameters of claim 1, wherein the step of calculating at least two impedance parameters from the at least one sensor comprises using changes of the complex impedance.
