This project introduces a self-powered, dual-node smart agrovoltaic system that integrates spectral light control with automated microclimate and irrigation management. Traditional protected agriculture relies heavily on unmanaged clear plastics, which often cause severe heat stress and cast harsh, static shadows when paired with overhead solar panels in agrovoltaic setups. To resolve these limitations, this system utilizes a red-filtered greenhouse canopy designed to isolate photosynthetically active red light wavelengths (630–660 nm) for optimized plant growth while mitigating thermal hotspots. Positioned directly beneath the red canopy, a 10W solar panel generates clean energy to power the entire system off-grid.

The architecture is divided into two operational IoT nodes: Node 1 utilizes an INA209 high-side sensor to monitor real-time panel power output (voltage, current, and wattage) alongside internal greenhouse ambient temperature, humidity, and light intensity, broadcasting live telemetry to a mobile Blynk interface. Node 2 operates a closed-loop soil moisture monitoring and automated irrigation unit that triggers a 12V water pump whenever soil dryness exceeds a pre-set threshold. Powered entirely by the harvested solar energy stored in a battery buffer, this integrated agrovoltaic prototype demonstrates a fully autonomous, energy-self-sufficient farming framework that harmonizes overhead solar generation with crop photobiology and automated resource management.
