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 ...

ThermaPID is a temperature control system implemented on Arduino using a DHT11 sensor, a brushless pc fan (5V 0.4A), and a PID controller. The fan speed is automatically adjusted via PWM to maintain a ...

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 goal of this project is to create a smart fan system that adjust its speed based on the current temperature. There are two modes: Manual and Automatic. Manual: The fan adjusts its speed based on ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

This paper presents an automated temperature monitoring and control system utilizing Arduino, designed to manage temperature-dependent operations efficiently. The system integrates an LM35 temperature ...

So Manual control choices looks like this: 0.75PWM value/Centigrade ~ 2.25 PWM value/Centigrade, with .5 increments in between. This may as well be Greek to me. I get that fan speed should increase ...
