Building a LoRaWAN Class A Sensor Node with ESP8266, BME680 and RYLR993

In this video, I’m building a LoRaWAN Class A sensor node using an ESP8266, BME680 environmental sensor, and REYAX RYLR993 LoRa module.
The device measures temperature, humidity, pressure, and gas resistance, then sends the data to The Things Network (TTN). I've also implemented going into deep sleep between transmissions to save power.

I’ll walk you through the full process from wiring and code setup to TTN configuration and payload decoding. This project is perfect if you want to learn how to make your own low-power IoT sensor or get started with LoRaWAN development.

🧠 What You’ll Learn
- How to connect the BME680 sensor to an ESP8266
- Setting up the REYAX RYLR993 module for LoRaWAN OTAA authentication
- Writing and uploading the Arduino code
- Configuring your device and decoder in The Things Network
- Using deep sleep for battery-friendly operation
- Monitoring live data and optimizing transmission power
