Controlled Fan System with Arduino Circuit Diagram

Controlled Fan System with Arduino Circuit Diagram In this article, you are going to learn about Arduino temperature controlled fan using DHT22 sensor and relay. We will use the DHT22 sensor to get the temperature value and we will print this temperature value on the LCD. Then we will check if the temperature value is greater than 35 or not, if the temperature will be greater than 35, then the

Most of the power electronics system use big heatsink to dissipate excessive heat. Some of these uses active cooling method, by using a fan on heatsink which help to remain the temperatures more stable. Using Arduino and temperature sensor we can make a temperature-controlled fan. More applications of this type of fan can be found in UPS

Temperature Controlled Fan with LM35 and Arduino Circuit Diagram

The fan speed is controlled by using PWM signals. And last part of the system shows humidity and temperature on LCD and Fan runs. Then we have programmed our Arduino according to the requirements. Working on this is very simple. We have generated PWM from Arduino and put it at the base terminal of the transistor.

project is very easy to make and the concept behind project is when we set threshold temperature when atmosphere temperature crosses threshold temperature it detects using temperature sensor and it turns on fan. I also provide video link above so you can follow that also if any trouble cause.  Now without wasting much time let's get started..

Arduino Based Temperature Controlled Fan Circuit Diagram

Using an Arduino, a DHT11 temperature sensor, a 5V fan, a potentiometer, and a 16x2 LCD display, we'll walk you through the process of building a temperature-controlled fan system in this tutorial. This project will give you a useful example of Arduino-based automation by enabling you to automatically change the fan speed based on the outside temperature.

Using a MOSFET like the IRF540N instead of a relay allows us to take advantage of PWM (Pulse Width Modulation) control, which enables us to adjust the fan speed smoothly based on temperature changes. A relay, on the other hand, would only allow us to turn the fan on or off, lacking the proportional control a MOSFET provides.
