本研究讨论了如何构建和分析一个915 MHz长距离(LoRa)E32基于频率的节点传感器网络,该网络具有一个微传感器,该微传感器具有3个传感器输出,即温度(DegC),气压(hPa)和湿度(%)。因此,本研究成功地使用LoRa E32 915 MHz使用迷你型ATmega 328p微控制器与3.7伏,1000 mAh电池制作传感器节点。接收器上的显示器使用8X2 LCD,将输出3个传感器数据输出。此外,本研究的结果和分析是如何分析LoRa Chirp信号,以及如何从Textronix频谱分析仪实时获得LoRa Chirp信号,服务质量(QoS),接收信号强度指示(RSSI)(-dBm),Internet服务器上的上行链路和下行链路数据。此外,微传感器图形输出将与传感器数据图形一起显示在应用程序服务器上。本研究中使用的应用服务器是Mathworks公司的Thingspeak。
This research discusses how to build and analyze a 915 MHz Long Range (LoRa) E32 Frequency-based Node Sensor network with a Micro Sensor with 3 sensor outputs produced i.e, Temperature (DegC), Air Pressure (hPa), and Humidity (%). therefore, This research succeeded in making a sensor node using the LoRa E32 915 MHz using a mini type ATmega 328p microcontroller with a 3.7 volt, 1000 mAh battery. The display on the receiver uses an 8X2 LCD which will output 3 sensor data outputs. furthermore, the result and analysis of this research are how to analysis of the LoRa Chirp Signal, furthermore, LoRa Chirp Signal obtained from the Textronix Spectrum analyzer in realtime, Quality of Service (QoS), Receive Signal Strength Indicator (RSSI) (-dBm), uplink and downlink data on the Internet Server. Furthermore, The Micro Sensor Graph Output will be displayed on the application server with a sensor data graph. In this research Application Server used is Thingspeak from Mathworks.
