Remote Laboratory Using Horizontal Axis Wind Turbine as Distance Learning Support

Remote laboratory is a system that allows users to access and control laboratory equipment via the internet remotely. Time and place limitations of the laboratory can be overcome by using a remote laboratory. The remote laboratory will use a horizontal axis wind turbine simulator. Remote laboratory system will use the Arduino Mega 2560 as the master and ESP32 as the slave which aims to transmit data on the website. Horizontal axis wind turbine functions as a simulator to produce the voltage and current generated by the generator. The wind source is obtained from a variation of 10 dimmer speed modes on the fan. The dimmer will be connected to the microcontroller so that the fan speed mode can be remoted via the website. The wind generated by the fan will rotate the turbine blades. The rotational speed per minute (rpm) of the turbine blades will be measured by the TCRT5000 sensor. So that there are 3 variables that will be measured using the sensor, namely voltage and current using INA219 and RPM using the TCRT5000. The results of INA219 and TCRT5000 readings will be displayed on a monitoring website which will be designed to support the distance learning process. INA219 sensor validation results obtained an error value of 1.51% and an accuracy of 98.49% for voltage and an error value of 3.37% and an accuracy of 96.63%. TCRT5000 sensor validation results obtained an error value of 2.08% and an accuracy of 97.92%. The system test results found that the blade 3 wind turbine cannot rotate at speed level modes 1 and 2. The blade 5 wind turbine is able to rotate at all speed level modes. The output of the blade 5 wind turbine has a higher voltage, current and RPM value when compared to the blade 3 wind turbine.
