In this tutorial, we will use an interface LoRa Module SX1278 with NodeMCU ESP8266 Board. We will make a transmitter and receiver circuit. We will display the transmitted parameters on a 0.96″ I2C OLED Display. We will take two examples of learning Lora SX1278 & ESP8266 Communication. First, we will transmit a simple packet and check whether is the data is received at the receiver end or not. Then we will add DHT11 Humidity & Temperature Sensor to the transmitter Circuit and send the humidity temperature value wirelessly to the receiver end.
