Perancangan Sistem Kontrol Suhu pada Budidaya Ikan Hias Berbasis Mikrokontroller Nodemcu ESP8266 dengan Internet of Things

Abstract

Ornamental fish are types of fish that live in fresh water or in the sea and are kept not for consumption but to beautify the garden/living room. Freshwater ornamental fish farming is a lucrative and very simple business, especially for guppy ornamental fish. Guppy fish growth is influenced by several environmental factors, one of which is water temperature. Guppy fish can live at temperatures of 22-34°C. And to maintain the health of guppy fish, a mechanical process and automation system have been successfully designed in the working mechanism of the tool in "Design of a Temperature Control System in NodemcuESP8266 Microcontroller-Based Ornamental Fish Cultivation with the Internet of Thing". For the initialization process. Sending sensor level values to the slave with the system using SPI communication and processing. Then the sensor measures and detects temperature with the MAX 6675 Thermocouple IC. If the temperature is above 34, the relay will be HIGH or have a logic 1 value and the fan will automatically turn on to cool the water in the aquarium. If the temperature is below 34 then the relay will be in a LOW state or a logic 0 value and the fan will automatically turn off. Then the sensor data will be displayed on the LCD. After that the measurement starts which will appear on the BLYNK application on mobile phones and also on the WEB system. And the data obtained to reduce the temperature from 36°C to 34°C takes 10 minutes with a volume of 20.592L of water, a height of 36cm of water and the location of the sensor from the surface of the water 32cm
