abstract = {IoT (Internet of Things) has become a separate research field since the development of internet technology and other communication media. IoT optimizes several tools such as sensor media radio frequency identification, wireless sensor networks and other smart objects that allow humans to easily interact with all devices connected to the internet network. The purpose of this research is to build an IoT-based solar cell tracker which can be controlled through mobile Apps and the data can be read anywhere as long as there is an internet network. In this research used LDR sensor, DHT11 sensor, Voltage sensor and MPU6050 sensor to optimize the performance of the proposed solar cell tracker system. The control system is built using an Appinventor that allows the system to be controlled via cellular phone from a distance. All sensors will be connected via Arduino and real-time data can be viewed through the Thinger.Io web page using Raspberry and mini LCD. ESP8266 NODE MCU microcontroller is used for a Wi-Fi connection. The results of this study indicate that the voltage value generated by dynamic solar cell tracker is greater than the static solar cell tracker. Dual axis sun tracker devices that are built using four LDRs produce an average voltage of 19.40 Volt when the sunny weather, 18.05 Volt when the cloudy weather and 13.60 Volt when the rainy weather.},
