Integrating RTC based scheduling and IoT override for organic fertilizer mixing: design, validation, and improvement roadmap
Keywords:
RTC based scheduling, IoT automation, Organic fertilizer mixing, Real time clock (RTC), Smart agriculture technologyAbstract
This study proposes and validates a hybrid control architecture based on the integration of Real Time Clock and Internet of Things for a laboratory scale automatic compost mixing system using an ESP8266 microcontroller with deterministic scheduling based on absolute time and remote monitoring and override functions. The prototype with integrated wiring that separates the low and high voltage domains demonstrates consistent schedule execution, override response within seconds, and average power consumption of approximately 135 watts or less than 1/10-kilowatt hour per 45-minute cycle. This two-layer architecture improves consistency compared to manual operator-based methods, although long term durability testing and field validation are still required, and contributes to the development of low-cost modular automation systems that are adaptive to connectivity disruptions.
