Temperature Monitor

A small GTKmm‑based utility that displays your system’s CPU core/package temperatures, NVIDIA GPU temperature, and battery status in a desktop window. Includes built‑in alerts if CPU exceeds 100 °C or GPU exceeds 75 °C.

---

Features

• CPU Temperatures
  Reads per‑core and package temperatures via lm-sensors.
• GPU Temperature
  Queries NVIDIA GPU temperature via nvidia-smi.
• Battery Status
  Shows charge level and state via acpi.
• Alerts
  Pops up a GTK window if CPU > 100 °C or GPU > 75 °C.

---

Requirements

• Linux with:
  • lm-sensors (sensors) configured
  • NVIDIA drivers + nvidia-smi (if you have an NVIDIA GPU)
  • acpi installed
• GTKmm 3 development libraries
• C++17 (or C++14/C++11) compiler

---

Installation

1. Install dependencies

   sudo apt update
   sudo apt install build-essential libgtkmm-3.0-dev lm-sensors acpi
   sudo sensors-detect       # follow prompts to enable /etc/modules

2. (Optional) Enable NVIDIA monitoring

   sudo apt install nvidia-driver-<version>

---

Building

Clone or copy the source into a directory, then:

g++ -std=c++17 -Wall -Wextra -o temperature_monitor tempmonitor.c++ \
    $(pkg-config --cflags --libs gtkmm-3.0)

---

Usage

./temperature_monitor

A window will appear showing:

• CPU Temperatures (per‑core + package)
• GPU Temperature (°C)
• Battery Status

If thresholds are exceeded, an alert dialog will pop up.
