Ensuring the freshness and safety of fish is vital to maintaining high quality seafood standards and consumer trust. Traditional methods of fish freshness evaluation such as manual inspection and chemical testing are often subjective, time consuming and unsuitable for large scale operations. To overcome these limitations, this paper presents Deep Fish Net, an intelligent and non invasive fish quality monitoring system that integrates sensor data acquisition with deep learning based image analysis.
The system employs an ESP32 microcontroller as the central control unit, interfacing with multiple sensors including a temperature sensor, ammonia sensor and ultrasonic sensor to monitor environmental conditions affecting fish freshness. A camera module captures real time images of fish samples on a conveyor belt mechanism driven by DC motors controlled through an L293D motor driver IC. Captured images and sensor data are transmitted to a server, where a Convolutional Neural Network (CNN) fine tuned using MobileNetV2 classifies fish into distinct freshness categories.
Experimental results demonstrate an impressive classification accuracy of 97.50%, outperforming conventional inspection techniques in both speed and reliability. Real time monitoring and alert generation through LED indicators and buzzer notifications are made possible. The proposed Deep Fish Net framework provides an efficient, accurate and scalable solution for automated fish freshness assessment, significantly enhancing food safety, reducing spoilage and improving quality control in seafood processing industries.
