Implementation of LoRa in River Water Quality Monitoring

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).

IoT Architecture Based Water Resources Conservation Management Using LoRa

Urbanization and anthropogenic activities are impacting the biodiversity of the water stream. Consequently, it interrupts water supply for daily purpose and sanitization requirement during pandemic Covid19. Water quality monitoring program designed to control water pollution. Development of IoT contributed to environment conservation including monitoring purpose for support decision system. This paper aims to study the integration of LoRa network with automatic water quality monitoring system. The proposed prototype of the system built with one gateway as base station and wireless sensor nodes (WSN) that embedded with water quality sensor of pH, turbidity, total dissolved solid (TDS), dissolved oxygen (DO) and temperature. The daily water quality status can be viewed in developed mobile application dashboard. Result shows that LoRa capabilities were affected from non-line of sight condition, transmission power and Spread Factor (SF) value. In conclusion, LoRa is compatible to be integrated with water quality monitoring system in urban environment. © 2021 IEEE.
