3. INTRODUCTION
• Electronic Fan is one of the most popular electrical devices due to its effectiveness and low power consumption
advantages. It is a common circuit and widely used in many applications.
• It is also one of the most sensible solutions to offer a comfortable and energy efficient. Nowadays, the demand for
accurate temperature control and air freshening control has conquered many industrial domains such as process heat,
automotive, industrial places or office buildings where air is cooled in order to maintain a comfortable environment
for its occupants.
• One of the most important concern involved in heat area consist in the desired temperature achievement and
consumption optimization. So, an automatic temperature control system technology is needed for the controlling
purpose in the fan speed according to temperature changes.
• Temperature fan speed controller is mainly build around thermistor, power transistor and few other components.
Thermistor is temperature dependent resistor its resistor increases with temperature decrease and resistance decrease
with temperature increase (it is negative temperature coefficient type NTC).
4. Objectives
1. Temperature based fan speed control
Adjust the fan speed dynamically in response to the rise in temperature.
2. Energy Efficiency
Minimize energy consumption by operating the fan only when necessary.
3. Automation
Develop a system that automatically senses temperature changes and adjusts fan speed without manual
intervention.
4. User comfort
Maintain a comfortable environment by ensuring appropriate air flow in response to rising temperature .
5. Safety
Prevent overheating in critical systems reducing the risk of equipment failure or fire hazards.
6. Applications
1. Temperature controlled fan can be used to control the temperature of devices, rooms, electronic components etc.
By monitoring the temperature.
2. The circuit can be used for car engine to reduce the heat.
3. Cooling pads in personal computers.
4. Automotive
5. Telecom equipment
6. Laptops servers and many portable and non-portable electronic devices.
7. Conclusion
This project elaborates the design and construction of fan speed control system to control the room temperature.
The temperature sensor was carefully was carefully chosen to gauge the room temperature. Moreover, the fan
speed will increase automatically if the temperature of the room increases. As conclusion, the system which was
designed in this project was tested, implemented in breadboard as well as soldered in board. It was performed
very well, for any temperature changes and can be classified as automatic control.
After completing this project I have learnt how to do soldering. How to make a circuit and implement it in the
board? Many a times I have to de- solder because of wrong connection and sometimes while doing the soldering
the circuit got shorted. The heating issue of op-amp was a great hindrance in our project. I learnt how to keep
patent and learnt many things about various new components. It was a very nice experience while doing the
experiment
