OUR OBJECTIVE: 1). Description: Temperature controlled Fan or Room Cooler using Arduino- In this project, you will learn how to make your own Fan, room cooler, ceiling fan or exhaust fan automatic temperature controller using Arduino, DHT11 temperature and humidity sensor, and a relay module.The Room Cooler or Fan is controlled automatically depending on the room temperature. It’s an ideal add-on for your PC cooling fans to eliminate produced noise. Temperature Controlled Fan Project 1. The second temperature controlled dc fan circuit project discussed below automatically senses the ambient temperature and adjusts the fan motor speed to keep the surrounding temperature under control. To minimize or reduce the power usage, this project developed an automatic fan system where speed is controlled by the room temperature… Hey guys again :) In this project i have tried to explain how to built Temperature Controlled FAN with an Arduino.... Basically i have used transistor in order to drive MOTOR. This project deals with the following: • Digital temperature sensor • PWM Based DC Motor Speed Control • Temperature controlled DC fan Usually, electronic devices produce more heat. Objective. So this heat should be reduced in order to protect the device. Sensed temperature in Celsius Scale and fan speed in percentage are simultaneously displayed on the LCD panel. Infra red remote control allows for manual override of the control fan speed. It uses a solid state relay so is silent in operation and more durable than using a mechanical relay. In the experiment, I used Arduino UNO as the main control board, processed the data collected by the DHT11 temperature and humidity sensor and controlled the 1602 display. The given project is a demonstration of such system. and once it crossed desired level then fan is turn on at low speed and the speed is increased with increase in temp. The working of the project is explained here. It is a resistance thermometer, its resistance changes inverse proportionally to the temperature. The project ‘Temperature Controlled Fan using arduino’ is simply fabricated around arduino uno board and temperature sensor LM35. Working: this project uses IC LM35 as a sensor for detecting accurate centigrade temperature. The FAN is controlled by a PWM wave given to it by the microcontroller, the power given to the fan is lesser in low temperature and greater in high temperature. Introduction 4. You can use this idea in your own laptop or you can make your own ventilator for the HOT SUMMER DAYS :). Circuit and working Fig. This project aims to achieve the purpose of efficient energy usage by providing an effective method of fan speed control as a function of instantaneous ambient temperature. Components Required For the simplicity of the circuit we have not included control to threshold level. The proposed system i.e. one having a negative temperature coefficient. This device allows me to configure at what temperature I want to automatically turn on a 230 VAC ventilation fan. Project Background: Sometime electric fan usage is wasting power because of human attitude. Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor.. The aim of this project is to design a temperature controlled fan using 8051 microcontroller, in which the fan is automatically turned ON or OFF according to the temperature. We have used a triac and firing cirucit in this project. Here is a simple circuit based on two transistors that can be used to control the speed of a 12 V DC fan depending on the temperature.A thermistor (R1) is used to sense the temperature. Our standard temperature controlled cooling fan kits will help you maintain the proper temperature of your computer, home theater cabinet, and more. The aim of this project is to automatically turn on or off the fan by detecting the surrounding temperature. Temperature Based Fan Controller 1. For this project you need any ESP8266 development board (a NodeMCU in this case), a DS18B20 temperature sensor, a mosfet module (eBay, AliExpress), a two wire computer fan and a 12v power supply or batteries.The 12 volts that the fan requires cannot be directly connected to … So all these are basic building blocks of temperature controller system.

Fig 2: Circuit diagram of Automatic temperature controlled fan using Thermistor . Schematic of DC Fan Controlled by Temperature Circuit Note by P Marian: this is an updated version of the old circuit designed by D Mohankumar that didn’t function at all. I had to remove the leds and use different values for R1 and R2 and now it works as you can see in the video below. This is a project demonstrating IOT (Internet Of Things) using platform of Arduino. For today’s tutorial, we will examine how a DIY version of this temperature-controlled fan can be built and deployed in your electronics project.

The temperature would be displayed through the LCD which is interfaced by the 8051 microcontroller. Here we are going to make a temperature controlled DC fan. temperature controlled fan circuit. For proper user interface visual indication we had also used LCD which indicate temperature as well as speed of fan. Use the Arduino kit in my hand to make a smart fan that automatically turns on or off and automatically adjusts to temperature. The value of thermistor resistance at 25°C is about 1 kilo-ohm. The applications areas of this project are air-conditioners, water-heaters, snow-melters, ovens, heat-exchangers, mixers, furnaces, incubators, thermal baths, and veterinary operating tables.
