Abstract

Electrical energy is one of the basic human needs whose use continues to increase along with the increase in daily activities. Uncontrolled electricity consumption can lead to energy waste and increased costs. Therefore, a system is needed that can monitor and control the use of electrical energy effectively. In this final project, we develop an Internet of Things (IoT)-based tool that is able to monitor and control the use of household electrical energy in real-time. This system uses ESP32 microcontroller, PZEM-004T current sensor, LCD to display the sensor output, and Relay as an automatic switch to regulate the on or off of electronic devices. Blynk platform is used as an intermediary between microcontroller and smartphone or PC to facilitate remote control. With this system, users can monitor daily energy consumption and control electricity usage efficiently, thus saving energy and costs. This research is expected to contribute to a smarter and more efficient management of household electrical energy

Abstract

Signaling devices such as signal lights and point machines are very important in railway signaling interlocking systems, where voltage and current affect their performance. Fluctuations in these parameters can cause malfunctions and endanger safety. Current manual monitoring is considered inefficient, error-prone, and slow to respond to problems. For this reason, an automatic monitoring system based on the Internet of Things (IoT) is needed to monitor parameters in real-time. The prototype uses two ESP32 microcontroller modules as data senders and receivers. Data is displayed via a TFT LCD screen and the Blynk application. The system is also equipped with a buzzer alarm to detect abnormal conditions. The test results show that the prototype monitoring device that was made can work well and in accordance with the design, where the PZEM-004T sensor is able to read current and voltage accurately and the buzzer alarm is able to detect when an abnormal condition occurs in the signaling device
