Sensor App

This is an Android application built with Jetpack Compose that demonstrates how to use the device's accelerometer sensor to collect and display sensor data, store the data in a local Room database, and visualize the data using the MPAndroidChart library.

Features

• Collects accelerometer data (x, y, z values) at a specified rate
• Displays the current accelerometer values on the main screen
• Stores the accelerometer data in a local Room database
• Exports the database data to a CSV file
• Displays line charts for the x, y, and z accelerometer values over time

Prerequisites

• Android Studio
• Android device or emulator

Getting Started

1. Clone the repository: git clone https://github.com/Sarthak-100/Sensor_App.git

2. Open the project in Android Studio.

3. Build and run the app on your Android device or emulator.

Usage

1. When the app starts, it will display the current accelerometer values on the main screen.

2. To export the database data to a CSV file, click the "Export Data" button. The exported file will be saved in the app's external files directory with the name "database_export.csv".

3. To view the line charts of the accelerometer data over time, click the "Go to Graph" button. This will navigate to a new screen displaying three charts: one for the x-axis, one for the y-axis, and one for the z-axis.

4. You can zoom in and out of the charts by pinching the screen.

Code Structure

• MainActivity.kt: The main activity of the app, responsible for setting up the Jetpack Compose UI, handling sensor events, and managing the Room database.
• AccelerometerData.kt: The data class representing an accelerometer data entry, annotated with @Entity for Room database integration.
• AccelerometerDao.kt: The Data Access Object interface for interacting with the Room database.
• AppDatabase.kt: The Room database class, providing access to the AccelerometerDao.
• SensorDataDisplay.kt: A Composable function that displays the current accelerometer values and provides buttons for exporting data and navigating to the graph screen.
• GraphScreen.kt: A Composable function that displays line charts for the x, y, and z accelerometer values over time, using the MPAndroidChart library.

Dependencies

This project uses the following dependencies:

• Jetpack Compose
