📡 Arduino Bluetooth Sensor App

📌 Description

This project is a React Native application that connects to an Arduino microcontroller via Bluetooth to receive real-time temperature and humidity data from a DHT11/DHT22 sensor. The app displays the collected data in a user-friendly interface, allowing users to monitor environmental conditions remotely.

🚀 Features

  • ✅ Bluetooth communication using HM-10 module
  • ✅ Real-time temperature and humidity monitoring
  • ✅ User-friendly UI for device selection and data display
  • ✅ JSON-based data exchange between Arduino and the mobile app
  • ✅ Support for future sensor integration

🛠️ Technologies Used

  • 🔹 React Native - Mobile app development
  • 🔹 react-native-bluetooth-serial-next - Bluetooth communication
  • 🔹 Arduino - Microcontroller for sensor readings
  • 🔹 DHT11/DHT22 - Temperature & humidity sensor

⚙️ How It Works

1️⃣ The Arduino reads temperature and humidity data from the DHT sensor.
2️⃣ The data is sent via Bluetooth in JSON format.
3️⃣ The React Native app receives and parses the data.
4️⃣ The values are displayed on the mobile screen in real time.

📲 Installation & Setup

🔹 Prerequisites

  • Install Node.js and React Native CLI
  • Setup Android Studio (for Android development)
  • Install Arduino IDE (for microcontroller programming)
