Hello friends! Today we will connect an LM35 temperature sensor to an Arduino Uno and reproduce the measurement in Proteus ISIS. We will start with the sensor's analog output, convert that voltage into temperature, and display Celsius and Fahrenheit readings on a serial terminal. Libraries Libraries used in this tutorial Arduino Library for Proteus: V2.0 (2021, used in this tutorial) · latest version: V4.0 (October 2026) Helping Tools Serial Monitor Advance : a serial terminal window for the UART of your board Serial Monitor Expert : the serial monitor with extra debugging tools LCD Library for Proteus V3.0 : 16x2, 20x4 and I2C LCDs to show your readings The circuit is small, but it teaches several important measurement concepts: ADC resolution, reference voltage, sensor accuracy and the d ...
