Abstract

The research entitled "Design of Water Replacement Equipment and Automatic Feeding in Microcontroller-Based Ornamental Fish Aquarium" is a development research on aquarium media for ornamental fish. This study aims to create a system where the system can work for water replacement, feeding, and automatic lighting in the aquarium automatically. This study uses Arduino Mega as a microcontroller board, turbidity sensor as a detector of turbidity in water, Real Time Clock IC DS1307 as an electronic clock to calculate real time conditions, Selenoid Valve as a valve that will be driven by solenoid electricity, Relay as an electronic switch, Liquid Cristal Display (LCD) to display text, Servo Motor as accelerometer and system speed control, ultrasonic sensor as signal detector, and pump used to drain liquid from lowlands to highlands. The results of this study show the tools that have been tested such as testing the RTC module which shows the RTC is connected to Arduino and LCD, testing the turbidity sensor which shows success in detecting water, testing the proximity sensor which shows an average difference in water of 1%, testing servo motor sensors that have worked quite well, testing the relay module for ON and OFF conditions get good information, testing the system as a whole that all systems work well according to what has been designed.

Abstract

Making this final project aims to realize the design of the tool and determine the performance of the Internet of Things (IoT)-Based Indoor Air Quality Monitoring System and can be monitored via Blynk, and also using an ESP32 microcontroller assisted by the mq-7 sensor, GP2Y1010AU0F sensor, and mq-135 sensors. This tool works to measure indoor air quality. Based on the tests that have been carried out, it can be seen that the overall performance of the Internet of Things (IoT)-Based Indoor Air Quality Monitoring System has worked as expected, namely when the sensor detects air quality, the results are processed by the ESP32 microcontroller so that it can be displayed on the LCD. After testing the tool from 07.00 to 18.00, the measurement results are obtained, namely the MQ 7 sensor when detecting CO gas of 228.47 ppm, the MQ 135 sensor when detecting CO2 gas has an average of 1, 12 ppm and the GP2Y1010AU0F sensor has an average of 1.50 kg/nm3 when it detects dust particles.
