Abstract
With the advancement of technology today, there is known to be an innovation that is the internet of things where electronic devices can be monitored and controlled remotely. For this reason, the practicum module of internet of things-based lighting installation as a medium of learning for students. The workings of the tool will be made using the PZEM-004T sensor as a sensor reading the current voltage, power, and energy used and ESP-32 as an additional module on the Arduino Mega so that data reading voltage, current and power can be sent using the internet network to the smartphone. In the smartphone application, we can also control to extinguish or turn on the lights.
Highlights
The PZEM004-T sensor will read the voltage, current and power in the practicum module and will be processed by ESP-32 so that voltage, current, and power readings can be sent to applications on the smartphone using an internet connection
In the smartphone application we can control the lights that are in the first, second and third groups by pressing a button in the application so that the ESP32 receives commands from the smartphone, the ESP-32 connected to the arduino will process the command, so that the relay can be active and turn on the lamp
The data is received by the ESP-32 using serial communications between the Arduino Mega and ESP
Summary
One example is the automation system of a device that can facilitate or provide comfort to humans. That the activities or work done becomes easier. Automation systems were originally only used in the industrial world to drive machines automatically. All kinds of systems can be automated in the field of industry. Another example of technology that is currently developing is the process of automation in the home. This system is often heard as a smart home
