Schematics Monitoring System Temperature, PH and Turbidity Based on LORA (Long Range) to Improve the Quality of the Harvest

Water quality in milkfish cultivation is an important role. The optimal temperature for milkfish is $28^{\circ}\text{C}$- $32^{\circ}\text{C}$ and has a pH of 7.5–8.5. In this study, a water quality monitoring system was made in the milkfish ponds which included temperature, pH, and turbidity based on LoRa (Long Range) communication. Testing of this tool uses an NTC temperature sensor and pH 4502-C is read and gets a value, if the value is in accordance with the standard value of the milkfish water quality, it will make a decision that the water condition is in good condition and if it does not match the standard value then the water condition is not doing well. And for turbidity using the DFRobot turbidity sensor, The results of the test can be displayed on think speak.
