If the temperature exceeds the maximum of the aforementioned "desired" range, then the LCD displays that the temperature is higher and tells to turn on the FAN. It may also be used for monitoring changes in environment. CIRCUIT DIAGRAM METHODOLOGY CHAPTER THREE Fig:3.2. This module will be controlling the speed of the fan based on the room temperature sensed by the sensor with the help of the code done in Arduino board. It's an issue with SpeedFan and not BatteEye, though. A simple project using microcontroller AT89S51 to control the speed of 12V fan according to the surrounding temperature.In this project we use the concept of PWM (pulse width modulation) to increase or decrease the speed of fan. Microcontroller (PIC16F877A) based speed control technique [58][59] [60] [61] has been implemented to control the speed of a ceiling fan. and once it crossed desired level then fan is turn on at low speed and the speed is increased with increase in temp. Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor.. It consists of 128 bytes of RAM, 16-bits of addresses, 16-bit timer/ counter-2, 6 interrupts ROM- 4k bytes. It’s an ideal add-on for your PC cooling fans to eliminate produced noise. Similarly the code for 25 will also vary for different fan speed, sleep settings etc. If the current temperature is greater than the set temperature the controller turns ON the fan and the set speed will be proportional to the difference between the set temperature & the current temperature. The microcontroller will send the PWM signal through pin-RC2 in port-C to the transistor which works as a control to the fan. The video below shows the fan speed changing when the temperature sensor is moved from cold water to hot water. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, These values are used to control the speed of the fan using PWM and the analogWrite(). Circuit diagram of the Temperature Based Fan Speed Control & Monitoring With Arduino & LM35 is shown above. As we are using PWM pin, the speed of fan is variable according to temperature. LCD shows the value of temperature and fan speed. Circuit description. When it comes to fan control, there is at the moment nothing that comes close in the usability department.

Lcd This module will be displaying the speed of fan-like zero, slow, medium, fast, very fast. The fanLCD re-maps the temp to allow the display of fanSpeed in a 0 to 100% range so you can say that the speed of the fan is directly dependent of the LM35’s temperature. This is to certify that the work in the thesis entitled Temperature Controlled DC Fan using Microcontroller by Ghana Shyam Soren, bearing roll number 111EE0236, and Ram Ashish Gupta, bearing roll number 111EE0211, is a record of an original research work carried out by them under my So it can save and streamline the work that is usually done manually which could then work automatically and effective for humans. The LM35 is a very simple temperature measurement IC. Phase angle control, achieved with triac technology, is used to adjust the motor voltage and to control the fan speed. Fig. A Raspberry Pi enthusiast, Jeff Geerling, released a pretty cool video showing how to add a fan to the Raspberry Pi to help keep the temperature under control.

Automatic fan speed control system using Arduino . If you're just doing the fan speed controller for fun, then here is what you need. e. Fan This module is to be controlled using all the other modules I don't know of any board that can control system fan speed based off GPU temp ... My Z170-E can monitor the GPU temp but can't adjust fan speeds around it. LM35 is a Celsius scale temperature sensor device with its output directly proportional to the temperature. This simple project controls the speed of a fan based on the reading from a temperature sensor. The duty cycle is made to vary according to the room temperature and the fan speed is controlled accordingly. TEMR:25 C FAN ON SPEED: LEVEL ONE Now agian updated temperature is read and is updated in the lcd by update function.This process maintains the status in LCD while temperature is changed. 5 Page ABSTRACT The purpose of making a final project entitled Automatic Fan Control System Based with Thermistor For Temperature Controller is to allow users to adjust the fan speed automatically. It not only monitors the speed of fans, but it can also control fan speed according to CPU temperature. Requested by some correspondents, this simple design allows an accurate speed control of 12V dc fan motors, proportional to temperature. According to the temperature sensor readings, the duty cycle will be automatically changed for controlling fan speed. Followings are the details of the project. Temperature is measured and displayed on LCD. CHAPTER THREE COMPONENTS METHODOLOGY 1. LM35(TEMPERATURE SENSOR) 2. The following code does rotate fan at certain minimum speed: msDelay(25); MTR=0; 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). Temperature based Fan Speed Control . Temperature Based Fan Speed Control Working. Circuit diagram of a temperature based fan speed controller 12. Seeing as SpeedFan hasn't really been updated since ~2015, I'd say figure out your Argus Monitor issues. (1) A way to measure temperature. According to this paper they used the following algorithm to control the speed of a fan according to temperature. It also shows the temperature on an LCD display and the temperature range from –55°C to +125°C. In our case fanSpeed will have a value of 32 at tempMin and 255 at tempMax. For example, when you decrease the temperature using the down button to make it 24°C (degree Celsius) you will get a signal with a set of data, but when you press it again to set 25°C you will not get the same data since the temperature is now 25 and not 24. If the current temperature is less than the set temperature the fan will be turned OFF. Arduino is at the heart of the circuit as it controls all functions. *Fans need to be connected to the following headers for AI Cooling control: CPU_FAN / CPU_OPT / CHA_FAN / M.2_FAN / H_AMP / RAD_FAN Ongoing monitoring AI Cooling continues to monitor the system and adjust fan speed based on current load. That project was pretty great but I wanted to take it to the next level and add the ability to only turn the fan on when needed by monitoring the core temperature. Thus, a brief summary of the controller is as follows: 1. SpeedFan is a free fan speed monitor software for Windows.

It is built around Arduino Uno board (Board1), 16×2 LCD (LCD1), temperature sensor LM35 (IC1) and a few other components. The main function of the microcontroller in the proposed system is to analyze the temperature which is sensed by the temperature sensor. Eg: To evaluate or To determine etc. You can hear the fan speed increase and see the readings changing on the Arduino IDE serial monitor. The circuit of automatic temperature controlled fan is build around temperature transducer AD590 followed by operational amplifier LM324. A thermistor is a resistor that varies its resistance based on temperature. Fig .3: Functional block diagram of Intelligent Temperature Monitor and PWM Fan Controller .

We also interface 2*16 characters LCD which shows the outside temperature through the temperature sensor. To control the case fans based on temperature of your GPU (or a combination of GPU and CPU or even disk temperatures or temperature readings of sensors on your motherboard) you should give Argus Monitor a try. 9. automatic temperature based fan speed controller system, triggering fan using rf remote and without, 10.
