Smart Compost Machine

Abstract— The "Smart Compose System" is an innovative project designed for real-time environmental monitoring and alerting. Managing organic waste is a major environmental concern, especially with rising cases of urbanization and agriculture.[1]. Conventional composting processes involve manual monitoring without automation, leading to low efficiency in decomposition as well as the production of bad smells. This article outlines the design and implementation of an IoT-based smart composting system employing an ESP32 microcontroller. In this system, monitoring of major parameters involved in decomposition, such as temperature, humidity, water content, and gas production , is done with the help of DHT22 sensors, soil moisture sensors, and gas sensors, respectively. A 12V DC motor is employed in this project for automating the mixing process within an aerated double-layer stainless steel compost box with the aim of enhancing microbial growth. The system results in increased efficiency with shorter decomposition times. Keywords—Kitchen Waste, Smart Composting, IoT, Sensors, Automation, Organic Waste
