Real-Time Grain Storage Monitoring System
Abstract
Efficient storage of food grains is essential for maintaining food quality and reducing post-harvest losses. Improper storage conditions such as high temperature, humidity, and gas accumulation often lead to spoilage, fungal growth, and pest infestation. This paper presents the design and implementation of an IoT-based Smart Food Grain Storage Monitoring System that continuously monitors environmental conditions inside the grain storage unit. The system utilizes an Arduino Uno microcontroller integrated with DHT22 temperature and humidity sensors and MQ135 gas sensors to detect variations in environmental parameters that may affect grain quality. The collected data is displayed on an LCD module and warning indications are provided through LED alerts when parameters exceed predefined threshold values. The proposed system reduces manual monitoring efforts and helps farmers maintain proper storage conditions. The developed prototype demonstrates a cost-effective and reliable solution for small-scale grain storage facilities, enabling improved grain preservation and reduced post-harvest losses.
