A novel on quality check of beverages using IoT

Beverage refers to a liquid food or drink which is normally consumed for its refreshing, appetizing and stimulating effects. Quality control is essential for any product being realized. It holds a main role in beverage industry to hold the product uniformity and dependability in order to ensure customer satisfaction, brand reputation and regulatory compliance. Beverage safety can be ensured through proper monitoring of the entire production chain. Ensuring the nutritional value ensures the quality of the product. Real time monitoring of beverages provide real-time visibility into the production process allowing to monitor critical parameters such as temperature, pH, color and dissolved oxygen. By detecting deviations in real-time, it can help in taking immediate corrective actions to prevent quality issues. The advent of IoT has revolutionized the food and beverage industry. Implementing IoT solutions in this sector can significantly enhance efficiency, quality control. This work presents an IoT based liquid quality analyzer system using a microcontroller (ESP32) in which multiple sensors are incorporated to measure pH, temperature, gas sensor and turbidity. The main objective is to provide a real time, accurate measurements for ensuring the quality check of commonly used beverages like Pepsi, 7 up and normal water. The analyzer system processes the sensor data using algorithms and displays the real time measured values using LCD display as well in graphical form.
