IoT Room Temperature & Humidity Monitoring

Project Overview

This project demonstrates a basic IoT system to monitor room temperature and humidity in real-time. It uses an ESP32 microcontroller and DHT22 sensor to collect environmental data and send it to a cloud platform like ThingSpeak or Blynk for visualization.

Features

• Real-time temperature & humidity monitoring
• Cloud storage and visualization (ThingSpeak/Blynk)
• Modular and scalable design
• Optional alert notifications

Hardware

• ESP32 Dev Board
• DHT22 Sensor
• USB power supply

Software / Technology Stack

• Arduino IDE
• ThingSpeak / Blynk
• HTTP / MQTT protocol

Usage

1. Clone the repository.
2. Open ESP32_DHT_ThingSpeak.ino in Arduino IDE.
3. Enter your Wi-Fi credentials and ThingSpeak API key.
4. Upload to ESP32.
5. View live data on your ThingSpeak dashboard.

Optional Enhancements

• Add more sensors (air quality, motion)
• Use MQTT for real-time push notifications
• Configure alerts for threshold breaches
