The Aquarium Monitoring System Design and Prototype for Ornamental Fish Farmers using NodeMCU with Telegram Data Notifications

In ornamental fish cultivation, water conditions are one of parameters to control the water quality. Water quality is closely related to fish habitat in ponds or aquariums. Water is a medium that must be considered because it supports the process of developing a successful fish culture. Because of the importance of monitoring water conditions for fish, some tools are needed to observe it in real-time. Therefore, pH level, oxygen, temperature and water transparency provide real-time notification of required time conditions. With the esp8266 microchip and built-in TCP/IP network software on NodeMCU has the ability to transmit data via Wi-fi, this data will be sent via the Telegram bot and the information of the state of the water, whether the pH is too low, the water is cloudy, and the water temperature. With some experimental test has some results about the accuracy level obtained on the pH sensor reaches the accuracy obtained is 99.19%. on the TDS sensor up to 96.7
^%
, the accuracy on the DS18B20 sensor is up to 96.9% and the last sensor is turbidity which has an accuracy of 49.73% so that this model can classify the water condition whether it is suitable for use for ornamental fish growth.
