Kjell Naessens developed and enhanced the Vertical-Farming-IB3/Plan-T system, focusing on robust water management, real-time sensor calibration, and energy monitoring for automated vertical farming. He designed and documented PCB hardware, implemented power and nutrient sensor calibration, and integrated ESP32-based IoT device control using C++ and YAML. His work included refining sensor data processing, improving pH measurement reliability, and enabling daily energy tracking through Home Assistant integration. By consolidating documentation in Markdown and optimizing hardware with KiCad, Kjell delivered maintainable, production-ready solutions that improved data quality, system reliability, and transparency, supporting both field deployment and commercialization of the platform.

May 2025 monthly summary for Vertical-Farming-IB3/Plan-T: Delivered end-to-end power monitoring and energy visibility, improved pH measurement reliability, and strengthened sensor data quality to support reliable automation and data-driven decisions. Implementations include a comprehensive power monitoring solution for the PCB with total power calculation including the UV lamp and a Home Assistant status sensor, plus daily energy consumption tracking to quantify energy usage over time. PH sensor reliability was enhanced by gating readings when the mixer is active and by refining sampling and filters to increase accuracy and stability. Added robust data filtering and noise reduction across Water/PCB sensors (including removal of invalid readings and median filtering for multiple sensors and ADC readings). These changes collectively improve data quality, enable more accurate dosing and energy optimization, and lay a foundation for proactive plant health and efficiency insights.
