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 ...

A temperature-controlled fan system that automatically adjusts the fan speed based on the environment using Arduino and DHT11 sensor. The system also displays the current temperature and humidity on a ...

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 ...

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 ...

The Arduino reads the temperature from DHT22 and adjusts fan speed using PWM. The current temperature is shown on the LCD.
