Abstract

An environment monitoring method including measuring data from a plurality of sensors, wherein each of the plurality of sensors includes a unique identifier (UID). The method further includes instructing each of the plurality of sensors to measure data. The method also includes receiving the measured data from each of the plurality of sensors. The method then calculates a product degradation value of a product based on the measured data and compares the product degradation value with a threshold product degradation value. In response to the product degradation value of the product exceeding the threshold produce degradation value, the method generates and sends an alert to a device.

Claims

1. An environment monitoring method comprising:

measuring data from a plurality of sensors, wherein each of the plurality of sensors includes a unique identifier (UID);

instructing each of the plurality of sensors to measure data;

receiving the measured data from each of the plurality of sensors;

calculating a product degradation value of a product based on the measured data;

comparing the product degradation value with a threshold product degradation value; and

generating an alert in response to the product degradation value of the product exceeding the threshold produce degradation value; and

sending the alert to a device.

2. The method of claim 1 wherein the measured data of each of the plurality of sensors includes:

a temperature, a relative humidity, a carbon dioxide level, and a location of each of the plurality of sensors.

3. The method of claim 1 further comprising storing the measured data of each of the plurality of sensors in a remote data storage.

4. The method of claim 3 further comprising transferring the measured data to the remote data storage via a reader, wherein the reader is configured to measure:

a temperature, a relative humidity, a carbon dioxide level, a location, and vibration.

5. The method of claim 1 further comprising indexing the measured data by product on a freshness calculation table, wherein the plurality of sensors are located in proximity to the product to trace the product along a supply chain.

6. The method of claim 5 further comprising accessing the freshness calculation table to calculate the product degradation value.

7. The method of claim 1 wherein the plurality of sensors are passive radio frequency identification sensors, and wherein a reader supplies power to the plurality of sensors in response to transmitting a read request to the reader.

8. The method of claim 1 further comprising:

determining a location of the product;

determining an operator device associated with the location; and

sending the alert to the operator device associated with the location.

9. The method of claim 1 wherein the threshold product degradation value is determined from a freshness calculation table.

10. The method of claim 1 wherein the UID is a radio frequency identification (RFID) tag, and wherein, to monitor the product along a supply chain of the product, the UID is located in at least one of:

(i) a shipping container, (ii) a trailer, and (iii) a cold room.

11. An environment monitoring system comprising:

a plurality of sensors configured to measure data, wherein each of the plurality of sensors includes a unique identifier (UID);

a reader configured to instruct each of the plurality of sensors to measure data and receive the measured data from each of the plurality of sensors; and

a freshness assessment module including;

a freshness calculation module configured to calculate a product degradation value of a product based on the measured data;

a freshness determination module configured to compare the product degradation value with a threshold product degradation value; and

an alert generation module configured to generate and send an alert to a device in response to the product degradation value of the product exceeding the threshold produce degradation value.

12. The system of claim 11 wherein each of the plurality of sensors measures data including:

a temperature, a relative humidity, a carbon dioxide level, and a location of each of the plurality of sensors.

13. The system of claim 11 wherein the freshness assessment module is included in the reader.

14. The system of claim 11 wherein the reader is further configured to measure data including:

a temperature, a relative humidity, a carbon dioxide level, a location, and vibration.

15. The system of claim 11 further comprising a freshness calculation table indexing the measured data by product, wherein the plurality of sensors are located in proximity to the product to trace the product along a supply chain.

16. The system of claim 15 wherein the freshness calculation module accesses the freshness calculation table to calculate the product degradation value.

17. The system of claim 11 wherein the plurality of sensors are passive radio frequency identification sensors, and wherein the reader supplies power to the plurality of sensors in response to the freshness assessment module transmitting a read request to the reader.

18. The system of claim 11 wherein the alert generation module:

determines a location of the product;

determines an operator device associated with the location; and

sends the alert to the operator device associated with the location.

19. The system of claim 11 wherein the threshold product degradation value is determined from a freshness calculation table.

20. The system of claim 11 wherein the UID is a radio frequency identification (RFID) tag, and wherein, to monitor the product along a supply chain of the product, the UID is located in at least one of:

(i) a shipping container, (ii) a trailer, and (iii) a cold room.
