Go Beyond WiFi and Build Reliable Connected Systems for Farms, Tanks, Outdoor Sites, Equipment, and Remote Locations
WiFi works well when equipment is close to an access point. But what happens when you need to collect information from a water tank, agricultural field, outbuilding, environmental station, or other location far beyond dependable WiFi coverage?
LoRaWAN and ESP32 IoT Projects shows you how to solve that problem step by step.
Written for readers with no previous experience in electronics, networking, or embedded programming, this practical guide takes you from your first ESP32 setup to complete long-distance communication systems capable of collecting measurements, transmitting compact messages, passing them through gateways, and delivering useful information to applications.
You will learn not only how to make the hardware communicate, but also how to design systems that remain efficient, secure, maintainable, and dependable in real-world conditions.
Inside, you will learn how to:
- Understand the difference between LoRa, LoRaWAN, WiFi, and MQTT
- Choose suitable ESP32 boards, radio modules, antennas, and peripherals
- Work safely with GPIO, SPI, I2C, power, and grounding
- Install Arduino IDE and prepare an ESP32 development environment
- Connect SX1276, SX1278, SX1262, and compatible radio hardware
- Send and receive your first point-to-point radio messages
- Measure signal strength and test communication distance
- Build temperature and humidity reporting nodes
- Understand end devices, gateways, network servers, and application servers
- Register equipment and configure OTAA activation
- Work with uplink and downlink communication
- Select the correct regional frequency configuration
- Configure and position a LoRaWAN gateway
- Forward information through MQTT
- Read and process JSON messages
- Encode measurements into compact payloads
- Decode transmitted information at the application side
- Reduce unnecessary airtime and oversized payloads
You will progress through several complete real-world builds, including a point-to-point temperature link, environmental monitoring station, remote water-level system, agricultural monitoring node, equipment and security alert installation, battery and solar-powered unit, and complete multi-node field network.
The final architecture brings everything together:
Measurement → ESP32 → Radio Uplink → Gateway → Network → Decoding → MQTT → Application
Rather than changing random settings when something fails, you will learn to identify the last point where the information is correct and troubleshoot from there.
You will also learn an important principle for remote installations:
Wake → Measure → Transmit → Sleep
That approach helps conserve energy while allowing small battery-powered units to operate for extended periods away from conventional infrastructure.
Whether you want to monitor farmland, water tanks, equipment, buildings, environmental conditions, or other remote assets, this book gives you a practical foundation for creating communication systems that can grow from one simple node into a complete field deployment.
Start with one measurement. Send it farther. Then build a network you can understand, test, and maintain.
