With this simple circuit you will be able to control the speed of a DC fan according to temperature measured by a temp sensor. Project Background: Sometime electric fan usage is wasting power because of human attitude. 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 … The circuit of automatic temperature controlled fan is build around temperature transducer AD590 followed by operational amplifier LM324. Mashud and his co-authors have conducted different tests and concluded that the fan speed can be controlled by room temperature using PT-100 sensor [6]. Temperature Controlled Fan Project 1. Temperature Controlled Fan: I have chosen to make a Temperature Controlled Fan for my final project this semester. 1. 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. Project Description. 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. The given project is a demonstration of such system. With a wide selection of easy-to-use, easy-to-install fans, we’re sure that you’ll find the best cooling solution needed for your next project. 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 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. The project will help save energy/electricity. Here we are going to make a temperature controlled DC fan. DHT22 sensor is used to sense the room temperature and then we adjust speed of a DC fan/motor accordingly using PWM (Pulse Width Modulation). To minimize or reduce the power usage, this project developed an automatic fan system where speed is controlled by the room temperature… and once it crossed desired level then fan is turn on at low speed and the speed is increased with increase in temp. This sensor is pulled for new data at a constant interval and will activate the high voltage circuit when the temperature becomes too hot. 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. So all these are basic building blocks of temperature controller system. 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. After hours of troubleshooting this circuit I finally f… This automatic processing is done through an Arduino and a temperature sensor IC LM35. Fan speed is varied depending upon the increased in temperature. temperature controlled fan circuit. Circuit diagram of the temperature fan speed control and monitoring is shown in Fig. Project Build a Temperature and/or Humidity Controlled Fan with a Picaxe 08M2 Microcontroller September 25, 2017 by Raymond Genovese A Picaxe 08M2 microcontroller and an HIH6030 sensor team up to easily control a ventilation fan using temperature or humidity or both. Project: Temperature Controlled Fan Using ARDUINO; Authors: Shwetha S Baligar. And also to assist people who are disabled and are unable to control the speed of fan. Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor.. Sensed temperature in Celsius Scale and fan speed in percentage are simultaneously displayed on the LCD panel. Read more Detail: Temperature controlled fan Low cost PCB at PCBWay - only $5 for 10 PCBs and FREE first order for new members Temperature Monitor and PWM Fan Controller: In this system for the monitoring of temperature the AMC6821 has been used. Components Required OBJECTIVE OF PROJECT Our object of making this project is for reducing the power consumption. The project ‘Temperature Controlled Fan using arduino’ is simply fabricated around arduino uno board and temperature sensor LM35.
