Abstract: Effective organic waste management plays a crucial role in sustaining soil health and reducing environmental burden, especially in small-scale farming systems and household settings where resources are limited. This paper presents the design and development of a semiautomated compost bin integrating sensor-based monitoring and automated aeration control to enhance composting efficiency and process consistency. Conventional composting practices, though widely used, often suffer from inadequate aeration, inconsistent moisture management, foul odour, and slow decomposition, leading to suboptimal compost quality and high labour dependence. The developed system integrates a DHT temperature and humidity sensor along with a resistive soil moisture sensor interfaced with an Arduino Uno microcontroller, ensuring continuous real-time monitoring of critical composting parameters. A relay-controlled 12V DC brushless fan mechanism is adopted to regulate forced aeration and maintain aerobic conditions whenever sensor readings deviate from the optimal range. The structure is designed to be lightweight, compact, and replicable using locally available components, making it economically viable for rural and peri-urban applications. Performance evaluation of the fabricated unit indicates reduced composting time by 40 to 50 percent, improved aerobic condition maintenance, better odour control, and reduced manual effort compared to traditional methods. The proposed system demonstrates the potential to bridge the gap between manual composting and large-scale mechanization by offering a practical, low-cost solution tailored for households, small farms, and educational institutions. This work contributes to advancing sustainable organic waste management practices at an accessible scale.
