I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

This project demonstrates how to control a fan (simulated with an LED) using an Arduino Uno and a temperature sensor. Below 25°C → Fan OFF 25°C to 30°C → Fan runs at 50% speed (PWM) Above 30°C → Fan ...

Automatic: The fan adjusts its speed based on the temperature retrieved from either a local temperature sensor or the OpenWeatherMap API. Compared to traditional fans, the smart fan aims to implement ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...
