Monitoring of pH, Amonia (NH3) and Temperature Parameters Aquaponic Water in the 4.0 Revolution Era

Abstract

The quality of the water is very important in determining the aquaponics system, including the pH parameter such as the ideal acidity level in aquaponics. The water quality temperature parameter also plays a very important role in determining water quality, especially in the case of temperature changes that are influenced by air temperature, wind speed and solar radiation. A safe maximum level of ammonia (NH3) is required in a good aquaponics system. When making adjustments, the water quality is set manually without the use of a controller that is fed back to the actuator, that is, the manual change of the desired temperature, pH value and ammonia. Temperature changes are made by exposure to sunlight or heating, while ammonia is achieved by adding fish feed or adding new water. Whereas the pH treatment is done with vinegar (for a pH value that is too humid), bicarbonate is used for a pH value that is too acidic for the research object. Based on the aquaponic system literature parameter data for ammonia from less than 0.5 ppm to an ideal of 0 ppm, the pH value is in the ideal range of 6.5 - 8, while at the ideal temperature it is (21-28 ) ° C. In this study, the author develops a solution to monitor the state of water with pH, ammonia and temperature sensors based on the Internet of Things, the Arduino Uno uses as monitoring parameters, pH sensors are They use to detect the acid content of water, temperature sensors for temperature measurements, use the MQ135 gas sensor for ammonia. and ESP8266 as a WLAN interface to send data to Android without using actuators.
