    Introduction

    Gravity: Analog LM35 Temperature Sensor for Arduino - Simple Analog Temperature Sensing for Arduino, ESP32, and Classroom Projects. A cost-effective LM35-based temperature sensor designed for learning analog input, reading ambient air temperature, and building basic indoor temperature monitoring projects. With a linear 10 mV/°C analog output, temperature changes can be read directly through a microcontroller ADC without using I2C, UART, or complex libraries.


    Who This Is For

  • Arduino and ESP32 beginners learning analog sensors
  • STEM education and classroom electronics projects
  • Basic indoor ambient temperature monitoring
  • Projects that need a simple, low-cost temperature input


    Core Difference

  • Linear analog output: 10 mV/°C
  • Direct voltage-to-temperature conversion
  • No digital protocol or sensor library required
  • Gravity connector and analog cable included for easier wiring
  • Works with 3.3–5V microcontroller boards


    • Why Choose This LM35 Temperature Sensor

    This LM35 temperature sensor is a practical choice for understanding how analog temperature sensors work. Compared with digital temperature and humidity sensors, it provides a simpler signal path, making it suitable for ADC experiments, voltage measurement lessons, and entry-level Arduino projects.

    Best used for basic ambient air temperature sensing in dry indoor environments.
