Abstract

This research aims to design and develop an Internet of Things (IoT)-based automatic water pump monitoring and control system. The system utilizes an ESP32 microcontroller connected to an ultrasonic sensor to measure water level and a turbidity sensor to detect water clarity. The pump is automatically activated when the water level drops below a specified threshold and deactivated when the tank is full. Furthermore, when the turbidity value exceeds a certain limit (e.g., >40 NTU), the system sends notifications to the user via the Blynk application. In addition, notifications are also sent through a Telegram bot, allowing users to receive alerts instantly without needing to open the Blynk app. Key data such as water level distance, NTU value, pump status, and water condition are displayed locally on a 16x2 LCD and remotely on the Blynk dashboard.System testing was conducted using samples of clean water, tea, and milk coffee to represent varying levels of turbidity. The results showed that the system effectively detected different turbidity levels and automatically controlled the pump based on the water level. This system offers an efficient real-time solution for monitoring water quality and can be applied in places such as Islamic schools (TPQ), educational institutions, or households.

Abstract

Server room security is a critical aspect of industrial operations, including at the Trangkil Sugar Factory, where all digital systems and production machine controls depend on the stability of IT infrastructure. The primary issue often encountered is unstable temperature or extreme humidity, which, if left unaddressed, can damage hardware components or even trigger fire risks due to electrical short circuits. This study aims to design an automated temperature, humidity, and smoke monitoring system based on the Internet of Things (IoT) to minimize these risks. The system was developed using the ESP32 microcontroller integrated with the DHT22 sensor for monitoring temperature and humidity, alongside the MQ2 sensor for smoke detection. The Research and Development (R&D) method was employed to ensure the system's accuracy in a real-world environment. Testing results indicate that the system provides a rapid response; if the temperature exceeds 21°C or humidity goes above 45%, a warning LED is activated. Furthermore, early warnings in the form of real-time notifications are sent directly to the technician's smartphone via a Telegram Bot, and a buzzer is triggered upon smoke detection. With this system, server room supervision becomes more efficient as it can be conducted remotely, allowing potential hardware damage to be prevented at an early stage.
