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.
