“…3) Lighting: The radiant flux required for the subjects of interest varies between species and organisms. Certain fungal species require white light while plant species mostly require red and blue components [24]. Literature have also indicated the changes in chemical composition in plants in response to red and far-red light [25], [26].…”

Use of commercial growth chambers for study of biological processes involved in biomass growth and production pose certain limitations on the nature of studies that can be performed in them. Optimization of biomass rearing and production process requires quantitative study of environment influences on the organism and eventually the products and byproducts consumed and produced. This work presents a low cost modular system designed to facilitate quantitative study of growth processes and resource exchanges in organisms such as plants, fungi and insect larvae. The proposed system constitutes of modular units each performing a specific function. A novel compact thermoelectric cooler based unit is designed for conditioning the air. Sensor cluster for measuring gas concentrations, air properties (temperature, humidity, pressure), and growing medium properties is implemented and tested. An actuator cluster for resource exchange and a wiring and control scheme for light spectrum adjustment is proposed. A three tier hierarchical software framework consisting of an open-source cloud platform for data aggregation and user interaction, embedded firmware for microcontroller, and an application development framework for test automation and experiment regime design is developed and presented. A series of experiments and tests were performed using the designed hardware and software to evaluate its capabilities and limitations. This controlled environment was used to study the photosynthesis and its dependency on temperature and light intensity in Ocimum basilicum. In a second experiment, evolution of metabolic activity of Hermetia illucens larvae over its larval phase was studied and the metabolic products and byproducts were quantitatively measured.

This paper presents the development of a cost-effective automatic system for greenhouse environment control. The architectural and functional features were analyzed in the context of the realization of a controlled-environment agricultural system through all its stages: installation, deployment of the software, integration, maintenance, crop control strategy setup and daily operation of the grower. The proposed embedded platform provides remote monitoring and control of the greenhouse environment and is implemented as a distributed sensing and control network integrating wired and wireless nodes. All nodes were built with low-cost, low-power microcontrollers. The key issues that were addressed include the energy-efficient control, the robustness of the distributed control network to faults and a low-cost hardware implementation. The translation of the supervisory growth-planning information to the operational (control network) level is achieved through a specific architecture residing on a crop planning module (CPM) and an interfacing block (IB). A suite of software applications with flows and interfaces developed from a grower-centric perspective was designed and implemented on a multi-tier architecture. The operation of the platform was validated through implementation of sensing and control nodes, application of software for configuration and visualization, and deployment in typical greenhouses.
