Abstract

With the advancement of wireless communication technology, appropriate solutions such as LoRa SX1278, a long-range intermediate module with a wider range of IoT applications have become available. Nevertheless, problems still exist, especially in Non-Line of Sight (N-LoS) circumstances that can favor transmission. On the other hand, the demand for more effective motors in the household sector is growing, where DC motors provide purchasing managers with advanced and low-cost direct control capabilities over AC induction motors. Suggested approaches include the use of omni-directional antennas to increase the transmission range of LoRa as well as the application of DC motors to improve operational efficiency. This work develops the necessary techniques to increase the communication range of LoRa and optimize the use of DC motors in a small industrial setting. The research procedure consisted of investigating the automatic control of a 12V DC motor using an Arduino Uno and a DHT22 temperature sensor, and the study of remote control via LoRa SX1278 with switching mode logic. The tests conducted confirmed that the percentage error of DC motor control was 0.78%, 0.42%, and 0.26% in each category, respectively. There is also a clear 600m and 6250m data transmission range on the LoRa in two different locations, featuring the same switching logic. In summary, the embellishment of LoRa SX1278 through omni-directional antenna anchoring and mode switching logic on the LoRa SX1278-based DC motor control system displays efficient operation and extended transmission range, thus offering antimicrobial potential in household industrial applications.

Abstract

The main problem in the highland area of Pesanggarahan Gordo Mulyo is the difficulty of monitoring and maintaining PLTS due to the remote location and no reliable communication signal. As a solution, this research developed a remote PLTS monitoring system using ESP32 and Handy Talkie communication, which allows automatic data transmission without internet connection. This research contributes to the optimization of the monitoring system adapted to the surrounding environmental conditions. Testing has 3 categories, in the PV solar panel monitoring test, the highest voltage is 37.1 V, the highest current is 2.1 A, and the maximum power generated is 81 W. Error calculations are also carried out to see the performance of the INA219 sensor with a multimeter measuring instrument, the test results for voltage, current, and power are 0.3%, 1.8%, and 1.26%. The last test is sending data in the form of voice through HT transmission, the data sent is similar to the data received in five tests. Based on each test, this tool has a small error rate, so it can be one of the innovations in the world of monitoring solar power plants.
