MA LPWAN based Wireless Sensor Node for Aquaculture Water Quality Monitoring System

The monitoring of water quality becomes a necessity in aquaculture system to ensure the growth and vitality of the fish. There exists several influencing factors to the water quality including acidity (pH), turbidity, dissolved oxygen and temperature level. As an alternative, the role of farmers could be replaced with a wireless sensor network (WSN) system with the aim of achieving efficiency, accuracy, and remote access. This study proposed the design of wireless sensor node to monitor water condition. The LoRa module was used as communication protocol between node sensor and the gateway due to its efficient power consumption along with wide transmission range which is very appropriate to be applied in aquaculture systems that are usually far away or have limited electricity resources. Based on the sensor node functionality testing, the sensor node could response the environmental changes appropriately. In the performance testing result the best delay was 189,4 ms which was founded on 40m communication range and 82byte of data. The increasing value of communication range also caused linearly increase of the packet loss.
