Digital Thermometer Using Arduino & LM35 | Full Simulation in Proteus + Code Explained
This tutorial is a step-by-step guide to designing and simulating a digital thermometer using Arduino Uno, LM35 temperature sensor, and an LCD 16x2 display in Proteus Software. Whether you’re a student, hobbyist, or IoT enthusiast, this project will teach you:
📊 How the LM35 Sensor Works: Learn about its linear output (10mV/°C) and calibration.
🖥️ Proteus Simulation Setup: From component placement to circuit connections—no prior experience needed!
🧠 Arduino Code Breakdown: Understand analog reading, temperature conversion, and LCD interfacing.
📈 Real-Time Temperature Display: See the simulated LCD update dynamically as "temperature" changes.
Materials Needed:
Arduino Uno Board (ATmega328P-based)
LM35DZ Temperature Sensor (accurate ±0.5°C)
16x2 LCD Display Module (HD44780 controller)
10kΩ Potentiometer (for LCD contrast adjustment)
Jumper Wires
Software Requirements:
Proteus9+ (free trial available)
Arduino IDE (for code compilation)
Why This Project Rocks?
Educational: Perfect for learning sensor interfacing, ADC, and LCD control.
Practical: Foundation for IoT projects (e.g., smart home thermometers).
Cost-Effective: Uses common components (under $20 for hardware!).
