Abstract

In an aspect, a dual-sensor waterproof temperature monitoring probe includes a first hollow tube having a first end and a second end. A first temperature sensor is located within the first hollow tube proximate the first end. A second temperature sensor located within a second hollow tube having a first end and a second end. The second hollow tube has a shorter length than the first hollow tube. A rechargeable power source is located in the first hollow tube proximate the first end. A handle permanently seals the second end of each of the first and second hollow tubes.

Claims (28)

1. A dual-sensor waterproof temperature monitoring probe for continuously monitoring internal food temperature and ambient temperature, comprising:

a first hollow tube formed with a first end and a second end;

a food temperature sensor located within the first hollow tube proximate the first end;

a second hollow tube formed with a first end and a second end, the second hollow tube having a shorter length than the first hollow tube and the second end flush with the second end of the first hollow tube;

an ambient temperature sensor located within the second hollow tube;

a rechargeable power source located in the first hollow tube proximate the first end;

a handle permanently sealing the second end of each of the first and second hollow tubes.

2. The probe of claim 1 , further comprising a pointed tip at the first end of the hollow tube.

3. The probe of claim 1 , the handle configured to prevent water from entering the hollow tube and being capable of retaining structural and chemical integrity at temperatures up to about 500 degrees Fahrenheit.

4. The probe of claim 1 , the power source being a rechargeable battery.

5. The probe of claim 1 , the power source being a supercapacitor.

6. The probe of claim 1 , the power source being located between the first temperature sensor and the first end of the first hollow tube.

7. The probe of claim 1 , further comprising a wireless transceiver circuitry configured to obtain data from the first and second temperature sensors and transmit the data to an external device.

8. The probe of claim 7 , the wireless transceiver circuitry including an alerter comprising a processor and memory storing computer readable instructions that when executed by the processor operate to:

analyze the data to determine one or more of a current temperature and a remaining cook time, and

generate an alert when the current temperature and/or the remaining cook time satisfy a predetermined condition.

9. The probe of claim 8 , the predetermined condition being determined on settings received at the wireless transceiver circuitry from an external device.

10. The probe of claim 1 , further comprising at least one contact pin configured to couple the power source to an external power supply to recharge the power source.

11. The probe of claim 10 , the handle covering at least a portion of the at least one contact pin such that the internal components of the probe are sealed from moisture while the contact pin is configured to couple to the external power supply.

12. The probe of claim 10 , the at least one contact pin coupled to a first printed circuit board, and the rechargeable power source coupled to a second printed circuit board, the second printed circuit board coupled to the first printed circuit board.

13. The probe of claim 12 , the handle completely surrounding the first printed circuit board.

14. The probe of claim 12 , the second printed circuit board being located in the first hollow tube.

15. The probe of claim 12 , the second printed circuit board including wireless transceiver circuitry.

16. The probe of claim 1 , further comprising an inductive charging circuit for wireless charging of the power source.

17. The probe of claim 1 , further comprising a power plug receptacle for coupling the probe with a power plug.

18. The probe of claim 17 , the power plug being a micro USB plug.

19. The probe of claim 1 , the second hollow tube located adjacent the first hollow tube.

20. The probe of claim 1 , the second hollow tube comprising a smaller diameter than the first hollow tube.
