Cargo and door sensor
Implementations for a system to receive a message indicating that an ambient light level measured by an ambient light sensor within a container exceeds a first threshold value or falls below a second threshold value; in response to the message indicating that the ambient light level exceeds the first threshold value, activate a cargo sensor; and in response to the message indicating that the ambient light level falls below the second threshold value, de-activate the cargo sensor.
1. A system comprising:
a memory device to store instructions; and
a processing device operatively coupled to the memory device, the processing device to execute the instructions to:
receive, from a light sensor, a first reading indicating a first light level in a container comprising a container door;
determine the container door is open in view of the first light level exceeding a first threshold value;
receive, from the light sensor, a second reading indicating a second light level in the container; and
determine the container door is closed in view of the second light level falling below a second threshold value.
2. The system of claim 1 , the processing device to:
de-activate a cargo sensor in view of the second light level falling below the second threshold value.
3. The system of claim 1 , the processing device to:
activate a cargo sensor in response to the first light level exceeding the first threshold value; and
collect, by the cargo sensor, a sample indicating a cargo state of the container, wherein the cargo state is at least one of empty, load initiated, unload initiated, or loaded.
4. The system of claim 1 , the processing device to determine the first light level exceeds the first threshold value when a predetermined number of samples of the first light level exceed the first threshold value during a time window.
5. The system of claim 1 , the processing device to determine a cargo area of the container is not secure when the first light level exceeds the first threshold value and a rate of motion exceeds a first motion threshold value.
6. A method comprising:
receiving, from a light sensor, a first reading indicating a first light level in a container comprising a container door;
determining, by a processing device, the container door is open in view of the first light level exceeding a first threshold value;
receiving, from the light sensor, a second reading indicating a second light level in the container; and
determining the container door is closed in view of the second light level falling below a second threshold value.
7. The method of claim 6 , further comprising:
de-activating a cargo sensor in view of the second light level falling below the second threshold value.
8. The method of claim 6 , further comprising:
activating a cargo sensor in response to the first light level exceeding the first threshold value; and
collecting, by the cargo sensor, a sample indicating a cargo state of the container,
wherein the cargo state is at least one of empty, load initiated, unload initiated, or loaded.
9. The method of claim 6 , wherein determining the first light level exceeds the first threshold value comprises determining a predetermined number of samples of the first light level exceeds the first threshold value during a time window.
10. The method of claim 6 , further comprising determining a cargo area of the container is not secure when the first light level exceeds the first threshold value and a rate of motion exceeds a first motion threshold value.
11. A non-transitory machine-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:
receive, from a light sensor, a first reading indicating a first light level in a container comprising a container door;
determine the container door is open in view of the first light level exceeding a first threshold value;
receive, from the light sensor, a second reading indicating a second light level in the container; and
determine the container door is closed in view of the second light level falling below a second threshold value.
12. The non-transitory machine-readable storage medium of claim 11 , the processing device to:
de-activate a cargo sensor in view of the second light level falling below the second threshold value.
13. The non-transitory machine-readable storage medium of claim 11 , the processing device to collect a sample indicating a cargo state of the container, wherein the cargo state is at least one of empty, load initiated, or loaded.
14. The non-transitory machine-readable storage medium of claim 11 , the processing device to determine the first light level exceeds the first threshold value when a predetermined number of samples of the first light level exceeds the first threshold value during a time window.
15. The non-transitory machine-readable storage medium of claim 11 , the processing device to determine a cargo area of the container is not secure when the first light level exceeds the first threshold value and a rate of motion exceeds a first motion threshold value.
