utmost importance. Temperature and gas levels are two important parameters that are useful for the safety of food during storage. Traditional methods of monitoring temperature and gas levels in storage units are timeconsuming and prone to errors. Moreover, these methods do not provide real-time monitoring and control, which can lead to spoilage, wastage, and compromised food safety.
by monitoring and controlling the temperature and gas levels in a storage unit. The system utilizes a DHT11 sensor to measure temperature and humidity levels, an MQ4 gas sensor to detect the presence of harmful gases, an exhaust fan that turns on when the temperature exceeds a certain threshold, and a NodeMCU controller to manage the sensors and fan. All data is transmitted to a Blynk server, where it can be monitored remotely using a mobile application. Through the provision of real-time monitoring and management of storage conditions, the initiative highlights the potential for the Internet of Things technology to enhance food safety and cut down on food waste.

1. INTRODUCTION The safety and quality of food products are critical concerns for consumers, producers, and regulatory bodies. Temperature and gas levels are two critical factors that affect the safety and quality of food during storage. Traditional methods of monitoring temperature and gas levels in storage units are time-consuming and prone to errors. The emergence of IoT technologies has opened up new possibilities for real-time monitoring and control of environmental conditions in storage units. In this work, the authors utilize a DHT11 sensor to measure temperature and humidity levels, an MQ4 gas sensor to detect the presence of harmful gases, an exhaust fan that turns on when the temperature exceeds a certain threshold, and a NodeMCU controller to manage the sensors and fan. All data is transmitted to a Blynk server, where it can be monitored remotely using a mobile application. The project demonstrates the potential of IoT technologies to improve food safety and reduce waste by providing real-time monitoring and control of storage conditions. The report provides a detailed description of the system's design, implementation, and testing, and evaluates its effectiveness in maintaining safe storage conditions for food products.
