LM35DZ Tutorial

In this video, you’ll learn how to measure temperature accurately using the LM35DZ waterproof temperature sensor with an Arduino Uno. We walk through the full process step-by-step — from understanding how the sensor works to wiring it correctly and uploading the Arduino code. The LM35DZ is a precision analog temperature sensor that outputs a voltage proportional to temperature (10 mV per °C), making it simple and reliable for DIY electronics, industrial monitoring, and IoT projects. Using a waterproof probe makes it ideal for liquid temperature measurement, environmental monitoring, aquariums, and outdoor applications. 🔧 What you’ll learn: How the LM35DZ sensor works Required components Wiring diagram explanation Arduino code walkthrough How to convert voltage to °C Testing and reading values on Serial Monitor 📦 Applications: Temperature monitoring systems, smart agriculture, water tanks, weather stations, and automation projects.
