        abstract = {The proposed system presents an Internet-of-Things (IoT [4])–enabled food spoilage detection unit that continuously monitors internal and external parameters affecting food freshness. It integrates a needle-type [3] DS18B20 [3] temperature probe [2], a DHT11 [2] humidity sensor [2]], and an MQ-3 [1] [1] gas sensor [1] [1][1]. The needle probe is inserted directly into the food material to measure its core temperature, providing a more accurate and earlier indicator of spoilage than air-based sensors. Data from all sensors are processed by a NodeMCU [4] microcontroller [4], which triggers a buzzer and display alert when threshold values are exceeded. The real-time information can also be transmitted through Wi-Fi for remote access. This combination of needle-based internal sensing and IoT [4] communication offers a low-cost, efficient, and reliable solution for food safety monitoring and reduction of wastage.},
