Automatic Sprinkler System for Water Efficiency Based on LoRa Network

The agricultural sector is an important sector for economic growth in Indonesia. This was indicated by the data from the Indonesian Ministry of Agriculture that stated the Gross Domestic Product (GDP) from 2013 to 2017 in the agricultural sector grew by 9.90%. Based on this data, a research that could help farmers in terms of improving the quality of their crops by providing plants with sufficient water intake was made. With this system, farmers will be able to monitor soil moisture using a laptop or a phone. In this research we evaluate the QoS of the communication between LoRa device. This system works by using a LoRa device operating at 433 MHz paired on 2 Nodes and 1 Gateway. Each node will be given 3 soil moisture sensors that will monitor soil moisture. Then, the sensor data will be sent to the gateway via a LoRa device. In the controlling mode, LoRa average delay and data loss are 196.96 ms (node1), 207.39 ms (node2) and 4.45% (node1), 10.03% (node2). That monitoring value is good value based on ETSI standard. But, in the monitoring mode, LoRa average delay are up to 10 s and average data loss are 6.67% from node1 and 13.34 % from node2.
