Abstract

An Internet of Thing (loT) device includes a head portion; an elongated stress sensor coupled to the head portion, the stress sensor coupled to a surface; a processor coupled to the stress sensor; and a wireless transceiver coupled to the processor.

Claims

1. An Internet of Thing (loT) device, comprising:

a head portion;

a stress sensor coupled to the head portion and to a surface;

a processor coupled to the stress sensor; and

a wireless transceiver coupled to the processor.

2. The IoT device of claim 1, comprising an elongated body enclosing the stress sensor and coupled to the head portion to form a bolt.

3. The IoT device of claim 1, comprising a washer coupled to the head portion, wherein the body comprises a threaded portion positioned through an aperture of the washer and wherein the stress sensor is positioned in a core of the threaded portion or adjacent a washer.

4. The IoT device of claim 1, comprising providing sensor data to a crowd and requesting from the crowd as a game one or more reasons explaining sensor data.

5. The IoT device of claim 1, comprising a processor coupled to the sensor and to a wireless transceiver in a recessed chamber.

6. The IoT device of claim 1, comprising a camera coupled to the processor.

7. The IoT device of claim 1, comprising an electronic nose or electronic tongue coupled to the processor for environmental detection.

8. The IoT device of claim 1, comprising a cloud based image processing system to receive images from the camera and recognize an image.

9. The IoT device of claim 1, wherein the stress sensor is coupled to a bolt, a screw, a stud or a fastener.

10. The IoT device of claim 1, comprising a wireless mesh network coupled to the wireless transceiver to transfer data from node to node.
