Abstract

The Supervision on Food Quality Using IoT System is an advanced monitoring solution designed to ensure optimal food storage conditions in real time. Utilizing an Arduino as the central controller, the system integrates a DHT11 sensor to measure temperature and humidity, MQ4 and MQ135 sensors to detect harmful gases like methane and ammonia, and a Peltier module with a heat sink for active cooling. A CPU fan, controlled by relays, regulates airflow to maintain stable conditions, while an LCD provides real-time data display. In case of unsafe conditions, a buzzer triggers alerts, and a GSM module sends SMS notifications. Additionally, the NodeMCU enables remote monitoring and control via Wi-Fi, ensuring efficient supervision of food storage. This IoT-based system is ideal for warehouses, cold storage, and food handling environments, helping reduce spoilage and maintain food quality.Keywords: ARDUINO, CPU fan, DHT11 Sensor, GSM module, NodeMCU, LCD.
