Implementation of Ultrasonic Sensor Using LoRaWAN Protocol for Monitoring Water Level in Aquaponic Pond

This research evaluates the effectiveness of implementing ultrasonic sensors utilizing the LoRaWAN protocol for monitoring water levels in aquaponic ponds. The study demonstrates that these sensors offer a remarkably high accuracy in water level monitoring. Accuracy testing reveals that each measurement yields an average of 87% and a maximum of 100% accuracy for each sample, with negligible variance between sensor measurements and manual readings. Furthermore, battery life assessment indicates a significant extension in battery longevity facilitated by the LoRaWAN protocol. The protocol's wireless communication efficiency enables periodic data transmission with minimal power consumption. Calculations suggest that with a delivery interval of 1 minute, the estimated battery lifespan is 1 year, while with 60-minute intervals, it may extend to approximately 66 years. This technology holds immense promise for enhancing the efficiency and dependability of monitoring systems in aquaponic farming, thereby contributing to sustainable agricultural practices.
