Prototype of Smart Garden System for Monitoring Holticulture Plants Based on LoRa Technology

This paper proposes a development of smart garden sistem based on LoRa technology. The basic principles of the control system in this study use a smart garden system that has the ability to send inputs in the form of data information that aims to monitor air temperature, air humidity, soil temperature, and automatic watering of ground kale plants which can be accessed through the Android application. The communication tool used is LoRa EBYTE E32. The LoRa EBYTE E32 module is used as a data communication module between the sensor node and the LoRa gateway, as well as the MQTT protocol as a data communication gateway. We introduce a new system monitoring plants based Internet of Things (IOT) which can be accesed through the android application on the smartphone. The Smart Garden system based on LoRa technology can work according to configuration because it can monitor air temperature, air humidity, soil temperature, soil humidity, and automatic watering of ground kale plants according to the configuration, namely the water pump is able to turn on when the humidity sensor has a range value below 80% is 20%-79% and the water pump shuts down when the humidity value exceeds 80%. Then, the communication coverage distance between the sensor node and the LoRa gateway after testing obtained the maximum distance is 440 meters in the Semi Line of Sight (LOS) area while in the Non Line of Sight (NLOS) area a lower maximum distance of 240 meters is obtained, this is because in the NLOS area there is an obstacle that hinders the coverage of the LoRa signal.
