Arduino Fan Speed Control Circuit Diagram Automatic control plays an ever-increasing role in a person's lifestyle. Automatic control is a vast technology area with a central focus on developing control strategies that increase productivity when applied to a system. A distinctive feature of automatic control is that it reduces the number of people-operators. One such gadget is a fan. Fans are usually available with variable speed
The document describes a project to control the speed of a fan using a microcontroller based on temperature readings from an LM35 temperature sensor. It uses an ATMEGA32 microcontroller to read the analog output from the LM35 sensor, convert it to a digital value, and generate a PWM signal to control the speed of a brushless DC motor fan. The 2N2222 NPN transistor acts as a controller switch which controls the speed of the fan by using the signal from the Arduino. The IN4007 Diode acts as a protection for the fan from being damaged. When the temperature exceeds the max temp the 5mm LED light glows. Working of the temperature based fan speed controller Circuit inconveniences associated in changing the Fan speed level manually when the room temperature changes. So, an efficient automatic Fan speed control system that automatically changes the speed level according to the change in environment / room temperature was implemented to solve the problems associated in Fan speed manual control

Automatic Fan Speed Control System Using Microcontroller Circuit Diagram
Temperature Based Fan Speed Control & Monitoring With Arduino: In this post, we have described how to design Temperature Based Fan Speed Control & Monitoring With Arduino and LM35 Temperature Sensor. The microcontroller controls the speed of an electric fan according to the requirement & allows dynamic and faster control and the LCD makes the Since the control of this rising temperature is not in our hands, we have built a project that helps us control the speed of the fan in a room depending on the rise and fall of the room temperature. This paper discusses temperature based fan control fan speed control and monitoring the system using an Arduino system. This microcontroller has inbuilt PWM module which is used for controlling the speed of the fan by changing the duty cycle. Fan Speed Control System using PIC16F877A Microcontroller. According to the temperature sensor readings, the duty cycle will be automatically changed for controlling fan speed. The microcontroller will send the PWM signal
