Controlling pH and temperature aquaponics use proportional control with Arduino and Raspberry

Abstract

In planting plants using an aquaponic system. Plants are very dependent on nutrients found in water, pH and water temperature. pH and temperature become one of the parameters that determine the yield. pH must be maintained in conditions 6.5–8.0 and temperature must be maintained at 18°-30° Celcius. Therefore, an automation system designed in order to keep the pH and temperature always at a predetermined range. Automation system designed using ARDUINO and RASPBERRY Pi microcontrollers with proportional control method. From the results of experiments that have been carried out, it is found that the designed device can control the temperature condition in the water by activating Peltier elements and fans or heaters to maintain the temperature conditions in water with fastest response time is 25.5 seconds for pH and 473.5 seconds for temperatures reaching setting determined.

Optimizing Nutrient Utilization, Hydraulic Loading Rate, and Feed Conversion Ratios through Freshwater IMTA-Aquaponic and Hydroponic Systems: An Environmentally Sustainable Concept

“…It can also be absorbed by microorganisms in the water column or bio lms associated with plant root mats [37][38][39] . pH stabilization is critical in aquaponics since it is required by every living species in a cycling system, which includes sh, plants, and microorganisms 40 . Each living component has a unique optimal pH.…”

Implementation system monitoring and control temperature and pH in urban silver catfish hatchery to enhance efficiency and responsiveness based on IoT

“…The test results are then compared against established standards to ensure that the system operates within the parameters set by the SNI. The system's success is measured through testing, including assessing the sensors' systematic error [34] and conducting black box testing on the programmed system to ensure validity [35], as detailed in Section 3. It is anticipated that the final results of the testing for this IoT-based monitoring and control system will enhance breeder efficiency and responsiveness.…”

Comprehensive Review of Aquaponic, Hydroponic, and Recirculating Aquaculture Systems

“…The automated hydroponic modular system (Figure 8) showed the methodology based on components Journal of Experimental Biology and Agricultural Sciences http://www.jebas.org and provides the pH value of the liquid fertilizer; if the level is insufficient, it will immediately activate the absorption of the solution into the container storage to afterward run the automated irrigation system for hydroponics (González-Linch et al 2019). Similarly, a computerization system is planned using raspberry microcontrollers and Arduino as a comparative management technique, and it could manage the water temperature and pH (Supriadi et al 2019). The dissolved oxygen content in an aquaponics system is increased by modifying the aquaculture water and the greenhouse environment (Ren et al 2018).…”
