ABSTRACT
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.
