Abstract

The end result of freshwater fish cultivation is in great demand by all levels of society both domestically and internationally. In Indonesia it increased by 115.16 percent in 2012. Freshwater fish have a range of abilities that are strongly influenced by natural limiting values, such as water temperature, turbidity and acidity (pH/Hydrogen Potential). It must continue to adhere to these constraints in order to survive. Because of these problems, we need a system that can be accessed from any location via the internet of things to monitor water quality. The DS18B20 sensor measures the temperature of the water in the pond or aquarium. The data sent by the ESP8266 microcontroller, which is used to interpret sensor data and convey sensor data via a wireless network, can be viewed via an Android application besides the microcontroller itself. The reading process takes place as soon as the system is turned on, and the sensor will communicate sensor data to the ESP8266 nodeMCU. NodeMCU ESP8266 will process data information to produce sensor measurement results. To display measurement result data on a smartphone, measurement results are stored in Firebase.
