Keywords:Design, Internet of things, Monitoring system, Real time, Single axis solat tracker
The purpose of this study is to describe the design, manufacture and testing of single axis online
solar tracker monitoring system with internet of things (IoT). The monitoring model consists of a series of
sensors with an Arduino control system and an online display of monitoring results displayed on thingspeak.
The solar panel are used in this study with a capacity of 30 WP. The testing process was carried out on the 5th
floor of the Department of Electrical Engineering, Universitas Negeri Padang. Data retrieval of monitoring
results takes place in real time and displayed in the form of graphic data, data information comes from sensors
connected to a microcontroller then connected to a WIFI module. Futhermore the data is sent to a thingspeak
server that can be accessed using notebook or android. Solar panels generate electricity from 7:00 am. to 18:00
pm for sunny weather, but for rainy weather the electric power decreases and disconnects earlier before sunset.
Test results show all data can be sent properly and can be directly monitored online. Thus, the solar tracker is
monitored effectively and efficiently where all data can be easily accessed with Android.
