Sensor Simulation System

Overview

This project implements a sensor simulation system with the following components:

• Sensor Device Simulator: Generates random temperature readings every 500 milliseconds.
• Data Logger: Periodically writes sensor data to a log file every 2 seconds.
• Command Interface: Allows external interaction via a Unix socket, supporting GET and STOP commands.

Requirements

• Requirements for each submodule:

1. Sensor Device Simulator:

• Runs in a separate thread and generates random temperature readings (e.g., between -50°C and 150°C) every 500 milliseconds. The generated data should be stored in a shared buffer (e.g., a queue protected by a mutex).

2. Data Logger:

• Runs in another separate thread and periodically writes sensor data to a log file "sensor_log.txt" every 2 seconds. It should append new readings without overwriting previous data.

3. Command Interface via Unix Socket:

• Listens on a socket "/tmp/sensor_socket"
• Accepts the following commands:
  • GET: Returns the last five temperature readings
  • STOP: Stops the simulation gracefully

4. Bash Script for Automation:

• Compiles the program: Runs the test scenarios and summarize the results

Build Instructions

1. Create a build directory:

   mkdir -p build

2. Go to the build folder

   cd build

3. Run the CMake

   cmake ..

4. Build project

   make ..

Running the Program

1. To run the main program(simulates the data)

   ./sensor_logger_simulator

2. Open a new terminal and run this command after running the previous command for about 3 seconds

  ./scripts/test_commands.sh GET

3. Stopping the simulation data stream

  ./scripts/test_commands.sh STOP

Automation Script

1. Run the automation script (Make sure that this is done after running sensor

  ./scripts/automation_script.sh
