Temperature Sensor Monitoring System (C++)

A console-based C++ application that simulates a temperature monitoring system using object-oriented programming principles.

---

Description

This project implements a TSensor class that represents a temperature sensor storing its latest 5 measurements.

The program allows:

• Creating and managing multiple sensors
• Reading sensor data from user input
• Calculating statistics such as average, minimum, and maximum temperature
• Comparing sensors using multiple approaches (member, friend, global functions, and operator overloading)

---

Features

• Object-Oriented Design (classes, constructors)
• Operator Overloading (<<, >>, >)
• Input Validation (sensor ID and temperature range)
• Statistical Analysis:
  • Average temperature
  • Maximum temperature
  • Minimum temperature
• Comparison of sensors using:
  • Member function
  • Friend function
  • Global function
  • Overloaded operator >
• Clean and formatted console output

---

How It Works

The program creates 3 sensors:

1. One using a constructor with parameters
2. One using the setData() function
3. One using user input (cin >>)

It then:

• Displays all sensor data
• Shows max temperature per sensor
• Checks if two sensors have identical measurements
• Compares average temperatures and displays the sensor with the highest value

Technologies Used

• C++
• Console (CLI)

How to Run

Using Dev-C++

1. Open the project
2. Add files:
   • main.cpp
   • TSensor.cpp
   • TSensor.h
3. Click Compile & Run (F11)

Using terminal (g++)

g++ main.cpp TSensor.cpp -o sensor
./sensor

---

Notes

• Temperature values are validated between -50°C and 100°C
• Sensor ID must be a positive integer
• The program demonstrates multiple comparison techniques in C++

---

Future Improvements

• Store multiple sensors dynamically (vectors)
• File input/output support
• Graphical interface (GUI)
• Real-time data simulation
