an IoT device communicatively connected to the IoT service over a wide area network (WAN), the IoT device comprising:
a light sensor to detect a change in visible electromagnetic radiation generated by a light source inside a refrigerator and responsively generate a signal; and
a secure communication module to receive the signal generated by the light sensor and to transmit a notification to the IoT service over the WAN to provide an indication of a status of a door of the refrigerator to the IoT service,
wherein the secure communication module is to periodically transmit additional notifications to the IoT service until the signal is no longer received from the light sensor, and
wherein the notification and additional notifications are stored in a storage of the IoT service and each comprises data indicating a respective date and time of the status of the door of the refrigerator associated therewith.
2. The system of claim 1 , wherein the change in visible electromagnetic radiation comprises a level of sensed brightness reaching or crossing a specified threshold.
3. The system of claim 1 , wherein the status comprises whether the door of the refrigerator is opened or closed.
4. The system of claim 1 , further comprising:
an IoT hub in communication with the IoT service and the secure communication module of the IoT device,
wherein the notification and additional notifications are transmitted from the secure communication module to the IoT service through the IoT hub and over the WAN.
5. The system of claim 1 , wherein the secure communication module is to start a timer responsive to receiving the signal generated by the light sensor.
6. The system of claim 5 , wherein the secure communication module is to transmit the notification to the IoT service when the timer reaches a particular value.
7. The system of claim 1 , wherein the secure communication module is to stop transmitting additional notifications to the IoT service when the signal is no longer received from the light sensor.
8. The system of claim 1 , wherein the secure communication module is to stop transmitting additional notifications to the IoT service responsive to receiving a second signal from the light sensor.
9. The system of claim 8 , wherein the second signal is to indicate a subsequent change in the visible electromagnetic radiation generated by the light source inside the refrigerator.
10. The system of claim 1 , wherein the IoT service is to generate one or more actions based on the notification and/or the additional notifications received from the secure communication module.
11. The system of claim 10 , wherein the IoT service is to generate the one or more actions when the notification and/or the additional notifications indicate that the door of the refrigerator has been left open for a specified time period.
12. The system of claim 10 , wherein the IoT service is to generate the one or more actions when the notification and/or the additional notifications indicate that the door of the refrigerator has not been opened for a specified time period.
13. The system of claim 10 , wherein the one or more actions comprise transmitting an alert to a client device of a user.
14. The system of claim 10 , wherein the one or more actions comprise transmitting a command to generate an alarm condition at a location of where the refrigerator is located.
15. A method comprising:
detecting, by a light sensor of an Internet of Things (IoT) device, a change in visible electromagnetic radiation generated by a light source inside a refrigerator and responsively generating a signal;
receiving the signal at a secure communication module of the IoT device;
transmitting, by the secure communication module of the IoT device, a notification to an IoT service over a wide area network (WAN) to provide an indication of a status of a door of the refrigerator to the IoT service;
periodically transmitting, by the secure communication module, additional notifications to the IoT service until the signal is no longer received from the light sensor; and
storing the notification and additional notifications in a storage of the IoT service, each of the notifications and additional notifications comprises data indicating a respective date and time of the status of the door of the refrigerator associated therewith.
16. The method of claim 15 , wherein the change in visible electromagnetic radiation comprises a level of sensed brightness reaching or crossing a specified threshold.
17. The method of claim 15 , wherein the status comprises whether the door of the refrigerator is opened or closed.
18. The method of claim 15 , wherein the notification and additional notifications are transmitted from the secure communication module to the IoT service through an IoT hub and over the WAN.
19. The method of claim 15 , further comprising:
starting a timer responsive to receiving the signal generated by the light sensor; and
transmitting the notification to the IoT service when the timer reaches a particular value.
