“…This study aims to create a system that can control electrical loads and can monitor them in real time and can even be controlled remotely using the internet, this system provides ease of use and flexibility in operating time because the user only needs to open the existing Adafruit server. on the website without the need to download the application first [27]. Based on Figure 3 it can be seen that the architecture of this system consists of 3 main parts namely, users, internet and servers, as well as electronic devices at home.…”

Utilization of modern technology is almost inseparable from the use of electrical energy. There is often the use of electrical energy that is actually not needed (wasteful), wasteful use of electrical energy results in increased costs, increased power supply, which has an impact on increasing equipment capacity, the problem of saving electrical energy has been widely discussed but saving electrical energy is easy and can be controlled automatically and can be monitored remotely still needs to be improved. Saving electrical energy can have an impact on cost savings, as well as prevent a crisis in the supply of electrical energy. According to data from the Ministry of Energy and Mineral Resources, the installed capacity of power plants for the 2018-2020 period increased by 2.34% per year. The distribution of electricity to customers in the 2018 – 2020 period has increased by 1% per year. Monitoring and controlling electrical energy can be done using controls using sensors and can be monitored and controlled remotely based on the internet of things. This study aims to design and manufacture a prototype tool that functions to monitor and control electrical loads in real time from a distance based on the internet of things and by utilizing sensors can also help turn on and turn off electrical loads as needed. The method used is through the stages of Analysis, Design, Development, Implementation, Evaluation (ADDIE). The results of the study show that the designed and manufactured tools can monitor electrical loads whether they are on or off and can turn on or turn off electric loads automatically with the help of sensors and actuators and can also be controlled remotely via smartphones, laptops, computers or tablets. Future studies are expected to be able to control electrical parameters including voltage, current, frequency, real power, reactive power, apparent power, and power factor. The expected impact of this research is that it can control electrical energy automatically easily and can control it remotely and save electricity usage.

“…The systems start the blocking mode and waits for the client to connect to the TCP server. Once the server receives the connection request from the client, the system creates new socket object and client address information for this connection, and finally conducts a test circuit experiment [7]. The socket is a JavaScript communication library for real-time web applications that uses WebSocket as the main transmission protocol, and plays an important part in TCP/IP transmission to enable real-time two-way communication between the server and the client.…”

We often need to identify the colors of such objects as buildings, clothing, photos, and traffic signs in everyday life. Some people cannot distinguish among such colors. This study proposes a method to help people, including colorblind people, identify colors. We establish a platform for color identification that is connected by the Internet of Things (IoT). The Espressif Systems 32 (ESP32) single chip is connected to a Wi-Fi communication network to transmit data to the color identification platform. The system interface is displayed in the form of color code and color name display. The speech synthesis module Speech Synthesizer Node 6288 (SYN6288) is used to broadcast color-related information. Since there are many color conversion technologies in modern times, or other color recognition methods are not applicable to the guide-blind function. Therefore, the authors use the method of reading out color-related information to directly enable colorblind people to conveniently identify the colors of objects. After experiments: the accuracy of various colors, the accuracy of environmental impact, the comparison of the original sensing experiment and the effect of adding interference light sources, the time required for color sensing to identify various colors, and the interference test results of any color light source, it is proved that the research mentioned in this research. The proposed method can not only improve the rate of recognition of the system in different environments, but can also accurately identify a variety of colors. The platform is integrated with the IoT to allow users to quickly monitor the displayed data.

This paper was discussed the hardware components of a remotely controlled water channel management system for laboratory education utilizing the internet of things(IoT) and supervisory control and data acquisition systems (SCADAs). The system consists of various sensors and devices included the air pressure sensor (mpx5010dp), water pressure sensor, ultrasonic distance sensor (JSNSR04T) and solenoid water valve plastic. The air pressure sensor (mpx5010dp) was used to detect the water level in the manometer of the pitot tube, a water pressure sensor for detecting the pressure of water, an ultrasonic distance sensor (JSN-SR04T) for detecting the level of water in the channel, a solenoid water valve plastic with relay for protecting the motor when the water level in the tank reduces to 5 cm. These components work together to monitor and control the water channel system remotely, providing users with a more scalable, flexible, and accessible solution for laboratory education. Also, a web page was developed with an IoT and SCADA system for remote control and management of a water channel system that was used for teaching hydraulic and hydrological concepts to students.
