Smart Agriculture Monitoring System Using Waveshare E-Paper Display & LoRa Module

Introduction

Modern farming requires real-time monitoring of soil, weather, and irrigation systems. Traditional farming methods lack automation and remote tracking.

In this project, we build a Smart Agriculture Monitoring System Using Waveshare E-Paper Display & LoRa Module that:

Monitors soil moisture
Tracks temperature & humidity
Displays data on low-power E-Paper
Sends long-range data using LoRa
Works in remote farm areas without WiFi

All required components are available at:

Why Use Waveshare Modules for Agriculture IoT?

Waveshare modules are ideal for smart farming because they provide:

✔ Ultra-low power E-Paper displays
✔ Long-range LoRa communication
✔ Industrial-grade reliability
✔ Raspberry Pi & ESP32 compatibility
✔ Clear sunlight-readable display

Perfect for rural deployments.

Hardware Required

👉ESP32 Development Board

👉 Waveshare E-Paper Display (2.9” / 4.2”)

👉Waveshare SX1262 LoRa Module

👉Soil Moisture Sensor

👉DHT22 Temperature & Humidity Sensor

👉Solar Panel + Battery (Optional)

How the Smart Agriculture Monitoring System Works

Step 1 – Sensor Data Collection

Soil moisture sensor measures soil water level.
DHT22 measures air temperature & humidity.

Step 2 – Local Display Using E-Paper

Data is displayed on Waveshare E-Paper:

Soil moisture %
Temperature
Humidity
Battery level

E-Paper consumes power only during refresh → ideal for solar farms.

Step 3 – Long-Range LoRa Transmission

Waveshare LoRa module sends data to:

Central Raspberry Pi gateway
Cloud dashboard
Remote monitoring app

LoRa reference:

Step 4 – Cloud Dashboard

Data can be uploaded via:

MQTT → https://mqtt.org/
ThingsBoard
Blynk IoT
Custom server

Basic ESP32 Code Logic:

#include <WiFi.h>
#include <DHT.h>

#define DHTPIN 4
#define DHTTYPE DHT22
DHT dht(DHTPIN, DHTTYPE);

void setup() {
  Serial.begin(115200);
  dht.begin();
}

void loop() {
  float temp = dht.readTemperature();
  float hum = dht.readHumidity();

  Serial.print("Temperature: ");
  Serial.println(temp);

  Serial.print("Humidity: ");
  Serial.println(hum);

  delay(5000);
}

LoRa data transmission can be integrated using SX1262 library.
