This paper presents Ecobin, a solar-assisted, IoT-powered self-cleaning and deodorizing trash bin that reuses collected rainwater for automated sanitation [1]. The system integrates an ESP32-S3 for sensor data and cloud monitoring, and an RP2040 for motor control via a Digital Loggers IoT Power Relay. The pump and winch activate a rotary sprayer, washing the interior of a 96-gallon outdoor bin. Experiments demonstrate effective cleaning (odor reduction up to 6 points) with low resource consumption (≈2.9 L water, 1.2 Wh energy per cycle) and high reliability (96.7%). Unlike existing smart bins that emphasize detection or waste sorting, Ecobin provides active hygiene maintenance, leveraging renewable water and safe electrical isolation for everyday usability. Future improvements include adaptive spray control, AI-based scheduling, and solar-power integration. Ecobin thus extends sustainable IoT waste management into the domain of self maintaining sanitation systems, merging ecological design with practical automation [2].
