Scent-based spoilage sensing refrigerator

A system, comprising:

• a computing device in data communication with a refrigerator, the computing device comprising a processor and a memory;
• and
• an application stored in the memory and executable by the processor, wherein the application is configured, when executed by the processor, to cause the computing device to at least:
• receive an identification of a food item located in a compartment of the refrigerator;
• determine a measurement interval for a chemical sensor in the refrigerator, the measurement interval being based at least in part on an internal temperature of the refrigerator or an amount of airflow in the refrigerator;
• cause the chemical sensor to take a plurality of chemical sensor readings at the measurement interval, wherein the plurality of chemical sensor readings individually represent a measurement of an amount of a chemical associated with spoilage of the food item present in the compartment of the refrigerator;
• receive at least one of the plurality of chemical sensor readings from the refrigerator;
• determine that the amount of the chemical associated with the spoilage of the food item exceeds a threshold amount of the chemical associated with the spoilage of the food item;
• and
• send a notification to a client device, the notification comprising an indication that the food item is spoiled.

A system, comprising:

• a refrigerator comprising:
• a compartment configured to contain a food item;
• and
• a chemical sensor configured to at least measure an amount of a chemical related to spoilage of the food item in the compartment;
• a computing device in data communication with the refrigerator, the computing device comprising a processor and a memory;
• and
• an application stored in the memory and executable by the processor, wherein the application is configured, when executed by the processor, to cause the computing device to at least:
• receive an identification of the food item located in the compartment of the refrigerator;
• determine a measurement interval for the chemical sensor in the refrigerator, the measurement interval being based at least in part on an internal temperature of the refrigerator or an amount of airflow in the refrigerator;
• take, via the chemical sensor, a plurality of chemical sensor readings at the measurement interval, wherein the plurality of chemical sensor readings individually represent a measurement of an amount of a volatile organic compound present in the compartment of the refrigerator;
• determine that the measured amount of the chemical related to spoilage of the food item exceeds a threshold amount of the chemical related to the spoilage of the food item;
• and
• send a notification to a client device, the notification comprising an indication that the food item is spoiled.
