Abstract

With the increased reliance on technology and smartphones, there is a growing need for quick and easy solutions to daily tasks. Amough them , food is a basic and necessary factor which plays an important role in human life, To prevent the consumption of spoiled food , we have developed a food detection system using Arduino. This system uses a microcontroller to interpret inputs and activate sensors. By detecting when certain perishable items are stored in the refrigerator for too long, it can help prevent food spoilage. The system continuously senses the signals from the food and displays the methane pH value on a LCD panel, accompanied by a buzzer and LED indicator.

Introduction

I. INTRODUCTION

Food plays a vital role in human life , hence having healthy food is of utmost importance for several reasons. Firstly, a nutritious diet is essential for maintaining good overall health. It provides the necessary nutrients, vitamins, and minerals that our bodies need to function properly, enhance the immune system, and prevent various chronic diseases such as obesity, diabetes, heart disease, and certain cancers. Secondly, healthy food plays a significant role in supporting brain function and mental well-being. Studies have shown that a diet rich in fruits, vegetables, whole grains, and lean proteins can improve cognitive function, boost mood, and reduce the risk of depression and anxiety. Furthermore, healthy eating habits contribute to maintaining a healthy weight. A balanced diet, coupled with regular physical activity, can help prevent obesity, which is a growing global health concern. Being overweight or obese increases the risk of several health problems, including diabetes, high blood pressure, and cardiovascular diseases. Having healthy food also promotes sustainable agriculture and the preservation of natural resources. A diet that focuses on plant-based foods, locally sourced and organic products, reduces the environmental impact associated with intensive livestock farming, excessive use of pesticides, and deforestation. It supports a more sustainable and ecofriendly food system that works towards mitigating climate change and preserving biodiversity. Food spoilage is a global concern that impacts the environment, economy, and public health. According to the Food and Agriculture 1 Organization (FAO), roughly one-third of the food produced for human consumption every year is lost or wasted. This amounts to approximately 1.3 billion tonnes of food, valued at over 1trillion. Food spoilage occurs due to various reasons, including microbial growth, enzymatic reactions, physical damage, and exposure to heat, light, and oxygen. It not only leads to financial losses for food producers and businesses but also contributes to greenhouse gas emissions and biodiversity loss. Moreover, consuming spoiled or contaminated food can cause foodborne illnesses in humans, leading to sickness, hospitalization, or even death. Implementing a food spoilage detector becomes imperative to address these issues and minimize the impact of food spoilage. Such a system utilizes advanced technologies like sensors, data analysis, and AI to monitor and detect signs of spoilage in real-time. By accurately assessing the freshness and quality of food product.

A. Problem Statement

The issue at hand is the pervasive problem of food spoilage and wastage, which has significant negative impacts on the economy, environment, and public health. Despite existing food safety regulations and quality control measures, effectively detecting and preventing food spoilage remains a considerable challenge throughout the food supply chain. Traditional methods such as visual inspection, smelling, and relying solely on expiration dates are subjective, time-consuming, and prone to human error. Therefore, there is a pressing need for an innovative solution that leverages the Internet of Things (IoT) technology to develop a food spoilage detector capable of real-time monitoring and early detection of spoilage indicators.

B. Objectives

The primary goals of this project are to develop a sophisticated IoT-enabled device capable of accurately detecting and identifying spoiled fruits. Our aim is to minimize food waste by ensuring the device has a high level of accuracy in detecting spoilage, thereby reducing unnecessary disposal of still edible produce. To achieve this, we plan to incorporate cutting-edge sensors, including methane sensors for measuring alcohol content and CH4 gas, to effectively determine the state of the food item.

Additionally, we seek to create a comprehensive system that can detect the earliest signs of spoilage, such as odors, enabling prompt removal of the affected product from the supply chain to prevent widespread contamination.

A. Project Design

A simple and effective approach for detecting spoiled food involves using an Arduino UNO prototyping board along with gas sensors like the MQ4 sensor to detect the odorous gases emitted by spoiled food. In addition to sending the signals to the server, the detection results can also be displayed to the user through a buzzer, LED, and LCD panel that are connected to the Arduino board. This proposed system provides an efficient and user-friendly way to detect and monitor the spoilage of food using readily available components and IoT technology.

C. Implementation

To implement a food spoilage detection system, you can utilize an MQ4 sensor that specifically detects methane gases. When fruits or other food items spoil, they emit these types of gases. The MQ4 sensor is capable of detecting the concentration of methane gases and providing an analog voltage output corresponding to the concentration level. Next, you can compare the detected values from the sensor to predefined threshold values using a predetermined algorithm. This comparison will help determine whether the food is fresh or spoiled based on the concentration of methane gases. Once the comparison is made, the values are sent back to the Arduino board. The Arduino board can then display the output on an LCD panel. The display will indicate whether the food is spoiled or fresh based on the food freshness level determined by the algorithm. By following this implementation process, you can create a reliable and efficient system that detects spoiled food based on the emissions of methane gases. This can assist in maintaining food quality and reducing the risk of consuming spoiled food.

III. RESULT AND DISCUSSION

The quality of the food can be continuously monitored using sensors, and the results can be conveniently displayed on an LED display. In the event that abnormal readings are detected by any of the sensors, such as the MQ4 sensor, a food spoiling message will be displayed on the LED screen. This immediate notification allows for prompt action to be taken to prevent the consumption of spoiled food. Furthermore, users have the ability to view the sensor values on the serial monitor of the Arduino IDE. This additional feature provides real-time data and enables users to closely monitor the freshness of the food. They can easily track any variations in readings and identify potential spoilage issues. By implementing this system, users can ensure the quality and safety of their food, as well as minimize the risk of consuming spoiled items. graph on the serial plotter of Arduino IDE.
