Abstract: Food security, economic stability, and public health are all greatly impacted by food safety and quality. In addition to causing serious illnesses, spoiled or infected food contributes significantly to food waste. Innovative approaches that integrate affordability, accuracy, and efficiency are needed to address these issues. The creation and deployment of Internet of Things (IoT)-based food quality monitoring systems that use inexpensive sensors to identify early spoiling indicators are the main topics of this review. In particular, the MQ4 methane sensor's interaction with NodeMCU and Wi-Fi modules offers a reliable way to keep an eye on gases released during food decomposition, such as ethanol and methane. In order to guarantee food safety, these devices provide real-time data to cloud-based platforms like the Blynk app, allowing for remote monitoring and prompt response.
