Overview

The Weather Monitoring System is a comprehensive IoT-based environmental monitoring solution built around the ESP8266 microcontroller that seamlessly integrates hardware sensors with cloud connectivity for real-time weather data collection and remote monitoring. This project leverages WiFi capabilities to create a distributed weather network that automatically uploads sensor readings to ThingSpeak every 10 seconds for continuous data visualization and analysis.

The system features dual monitoring interfaces including a local web server for immediate data access and cloud synchronization through ThingSpeak's IoT platform. With support for temperature, humidity, pressure, and rainfall measurements, this weather station provides comprehensive environmental monitoring suitable for agricultural applications, research projects, and personal weather tracking with both local and remote accessibility.

Getting Started

Prerequisites

Before getting started with weather-monitoring-system, ensure your development environment meets the following requirements:

• Development Environment: Arduino IDE 1.8.0 or newer with ESP8266 board package
• Microcontroller Hardware: ESP8266 development board (NodeMCU, Wemos D1 Mini, or equivalent)
• Sensor Components: DHT11/DHT22 temperature-humidity sensor, rain sensor module, connecting jumper wires
• Network Infrastructure: Stable WiFi network with internet connectivity for ThingSpeak integration
• Cloud Platform: Active ThingSpeak account with API key for data logging and visualization

Installation

Install weather-monitoring-system using the following comprehensive setup process:

Hardware Assembly:

1. Connect DHT sensor to ESP8266:

❯ DHT VCC → ESP8266 3.3V (Power Supply)
❯ DHT GND → ESP8266 GND (Ground Connection)
❯ DHT Data → GPIO2 (D4 pin on NodeMCU for data communication)

2. Connect rain sensor module:

❯ Rain Sensor AO → ESP8266 A0 (Analog input for rain intensity)
❯ Rain Sensor VCC → ESP8266 3.3V (Power supply)
❯ Rain Sensor GND → ESP8266 GND (Ground connection)

Software Configuration:

3. Install Arduino IDE and add ESP8266 support:

❯ File → Preferences → Additional Board Manager URLs
❯ Add: http://arduino.esp8266.com/stable/package_esp8266com_index.json
❯ Tools → Board → Boards Manager → Search "ESP8266" → Install

4. Install required libraries through Library Manager:

❯ ESP8266WiFi (included with ESP8266 board package)
❯ ESP8266WebServer (included with ESP8266 board package)
❯ DHT sensor library (by Adafruit)

5. Clone repository and configure credentials:

❯ git clone https://github.com/vipu18/Weather-Monitoring-System
❯ Open Weather.ino in Arduino IDE
❯ Update WiFi credentials and ThingSpeak API key

Usage

Deploy weather-monitoring-system using the following operational workflow:

System Deployment:

1. Configure network and cloud credentials in Weather.ino:

const char* ssid = "your_wifi_name";
const char* password = "your_wifi_password";
const String apiKey = "your_thingspeak_api_key";

2. Upload code to ESP8266:

❯ Tools → Board → NodeMCU 1.0 (ESP-12E Module)
❯ Tools → Port → Select appropriate COM port
❯ Sketch → Upload (Ctrl+U)

Monitoring and Data Access:

3. Monitor system status through Serial Monitor:

❯ Tools → Serial Monitor (115200 baud rate)
