ENSURING FOOD QUALITY BASED ON IOT

Le résumé fourni par la source

The objective of this project is to create a food quality sensor system utilizing the Arduino platform and a DHT-11 temperature and humidity sensor and the MQ-3 alcohol vapour detection sensor .The system provides a cost-effective solution for monitoring the freshness and safety of perishable food items. The DHT-11 sensor is employed to measure the temperature and humidity levels inside a food storage container. By monitoring these parameters, the system can determine whether the storage conditions are suitable for maintaining the quality of the food. If the temperature or humidity deviates from the desired range, the system can trigger an alert to notify the user. The MQ-3 sensor is utilized to detect alcohol vapour, which can be an indicator of food spoilage or contamination. When certain foods undergo decomposition, they release volatile compounds such as ethanol. The system can now detect the presence of alcohol vapours and generate an alert if detected beyond a predetermined threshold thanks to the integration of the MQ-3 sensor. The central processing unit for gathering data from the sensors and carrying out the required algorithms is the Arduino microcontroller. It interfaces with the DHT-11 and MQ-3 sensors to retrieve sensor readings. These readings are then processed to determine the food quality status. The Arduino can be programmed to send notifications via SMS, email, or other communication methods to inform the user about any potential issues. Overall, this food quality sensor system provides a cost-effective and easily implementable solution for monitoring the freshness and safety of food items. It can be utilized in various settings, including homes, restaurants, or food storage facilities, to ensure that the stored food remains within optimal conditions and to prevent the consumption of spoiled or contaminated items.
