Trasmitter LoRa Code Receiver LoRa Code

This project demonstrates long-range data transmission using LoRa LR-01 modules between KPZ and FTSM at Universiti Kebangsaan Malaysia (UKM). A transmitter placed at KPZ sends environmental sensor data to a receiver located at FTSM.

Using ESP32 and Arduino framework, the modules were programmed to send and receive messages while capturing RSSI (Received Signal Strength Indicator) values for signal quality analysis.
