A Performance of ES920LR LoRa for the Internet of Things: A Technology Review

In this research, the LoRa used is the ES920LR. LoRa ES920LR is used in Japan with a frequency of 920 MHz, LoRa ES920LR has small dimensions, its size is 24.00 x 17.0 x.2.3 mm, and a range of 3 km at Free Space Path Loss (FSPL); the RSSI value (-dBm) is found to be different in different outdoor environmental conditions. Furthermore, the ES920LR is used as a transmitter and receiver for human heart rate data. The heart rate sensor used is a Pulse Sensor placed on the tip of a human finger. At the Line-of-sight of Building position, the RSSI value (-dBm) shows -119 dBm at a distance of 710 meters, and the PRR (%) is 93.94%. Furthermore, the ES920LR is combined with the Leafony Board to become the Leafony Board LoRa ES920LR. Due to its small size, it is possible to place it on a drone or UAV coupled with GPS as navigation in the analysis and analysis of the ES920LR Spreading Factor and Signal Power LoRa.
