As the times goes and technology grow up so fast, so that we made a water quality monitoring system in the aquarium and it can be monitoring remotely. Monitoring the quality of water in aquarium can help those who need it, especially the people who like the most ornament fish. Monitoring water quality use 2 parameters, namely temperature and turbidity. The temperature parameter use the DS18B20 sensor and Turbidity parameter use the Turbidity sensor. Arduino Uno is use as controller and data processor and the data is sent using LoRa 915MHz to Arduino Uno then data will be displayed on serial monitor and LCD. The test have been working well. The temperature sensor is able to detect temperature values in the range -55?C-125?C. Turbidity sensor are able to measure the level turbidity where the value will decrease and if the water is clear the value will increase. And the LoRa 915MHz is able to send and receive data as far as 1180 meter at an hight of 44 meters and 450 meters at an hight of 16 meters.} }
