Development of Water Quality Control and Monitoring System for the Red Tilapia Fish in the Floating Basket Using IFTTT Model and IOT Based OSS

Abstract

This research aims to develop a water quality control and monitoring system for the red tilapia fish in the floating basket using the IFTTT Model and IoT-based OSS. The control system is the control of the Venturi Aeration. There will be 2 types of operation: Automatic (ON) will work in IFTTT, it is O₂ less than 3.0 milligrams per liter will do Venturi aeration, and Manual (OFF) is that it can be turned on and off by itself with a Smart Phone and a water quality monitoring system, which is to monitor abnormalities, acidity or alkalinity of the aqueous solution (pH), the amount of dissolved oxygen in water (DO) and water temperature (Water Temperature). Both systems consist of two parts; (1) the hardware part has the NodeMCU ESP8266 as the mainboard to receive data from 3 sensor devices, PH Sensor, Temperature Sensor, and Oxygen Sensor send the data via Wifi to the cloud server. (2) The software part will receive data from Arduino IDE, store it in Mysqli, and display it through a Web browser developed with PHP Language, which has 4 display screens: PH, Temperature, Oxygen, and buttons to select the mode of operation of Venturi Aeration, it can display a line graph of data from all 3 Sensors, view data in Realtime and store data for 24 hours. Testing the accuracy of the sensor device by conducting water supply and water from natural water sources in the area of ​​Chom Thong Subdistrict, Mueang District, Phitsanulok Province, 10 sources. Then perform the calibration with the standard. Multiparameter Water Quality Meter, whose calibration results were found to be within acceptable standards.
