This research study on the performance of Dragino LoRa 915 MHz by sending Moisture soil sensor data, there are two stages of LoRa communication system, i.e., Simple Communication and Communication Server LoRa 915 MHz uses LG01-P. The communication test sends data to the server with the uplink and downlink process that there is an ACK process from the server with moisture soil sensor data. It is also necessary to consider the power consumption factor. Therefore, it is essential to apply the Adaptive Data Rate Algorithm. And analyze the RSSI LoRa 915 MHz. Therefore, the results are actual analysis data in the field or outdoors and ensure that the LoRa IoT system can be well-received on Smartphone or desktop platforms with an internet connection.
