ABSTRACT
Emergence of Long Range (LoRa) in network technologies become game changer for Internet of Things (IoT) application. Deployment of LoRa enable IoT application of environment monitoring to cover wide area while maintain at low energy and low cost. Water quality monitoring program was developed to maintain and protect quality of water resources for daily purpose. Also, to prevent pollution and disease epidemic peculiarly during Covid19. This research aimed to build autonomous water quality monitoring prototype implemented with LoRa network for support decision system. The Wireless Sensor Nodes (WSN) that embedded with five type of water quality sensors of pH, turbidity, total dissolved solid (TDS), dissolved oxygen (DO) and temperature linked to single gateway. Water environmentalist able to view the result of timely water quality from mobile application dashboard. Though the performance not severely affected, acquired results revealed non-line of sight condition, transmission power and Spread Factor (SF) value influenced LoRa performance in urban environment. In conclusion, a few improvements on the system grant LoRa high capabilities to be integrated with IoT environment application in urban environment. © The 2022 International Conference on Artificial Life and Robotics (ICAROB2022).
