This project demonstrates how to measure temperature using an LM35 analog temperature sensor interfaced with Arduino. The sensor outputs a voltage proportional to the temperature, which Arduino reads, converts to Celsius, and displays or processes accordingly. This project teaches sensor interfacing, analog-to-digital conversion, and real-time temperature monitoring in a simulated environment. 1. Learn how to interface an LM35 temperature sensor with Arduino. 2. Understand analog-to-digital conversion and voltage-to-temperature mapping. 3. Explore programming techniques for reading, processing, and displaying temperature data. 4. Gain practical experience in designing basic temperature measurement and monitoring circuits.
