- 3. Introduction This practical temperature controller controls the temperature of any device according to its requirement for any industrial application, it also has a feature of remote speed control. The LM-35 Analog Temperature device is interfaced to analog pin of Arduino board, where it has built in ADC which converts these analog reading and displays it on a LCD, which indicate the temperature of the device. User-defined temperature settings can be done using push buttons provided through Arduino board.
- 4. Hardware Requirements Arduino develop board LCD High speed DC motor Temperature sensor.
- 5. Software Requirements Arduino Software Language: Embedded C .
- 6. Arduino Board Arduino is a single-board microcontroller. Intended to make the application of interactive objects and environments more easier. Basically this is very user friendly. There is a microcontroller unit embedded on it. The code is directly loaded from the computer.
- 7. Continue....... The Arduino microcontroller is an easy to use yet powerful single board computer. It has gained considerable traction in the hobby and professional market. The Arduino is open-source. Which means hardware is reasonably priced and development software is free.
- 8. DC Motor Brushless DC electric motor is a device powered by a DC electric source via an integrated power supply It produces an AC electric signal to drive the motor. It can give up to 10,300 rpm.
- 9. Liquid Crystal Display (LCD) Most common LCDs connected to the microcontrollers are 16x2 and 20x2 displays. This means 16 characters per line by 2 lines and 20 characters per line by 2 lines, respectively. The standard is referred to as HD44780U, which refers to the controller chip which receives data from an external source (and communicates directly with the LCD.
- 10. LM 35 Temperature Sensor LM35 are used to sense the heat and an IC ADC0808 is used to convert the data into digital. LM35 digital sensor has got 3 pin’s i.e., VCC, GND and output pin’s when LM35 is heated the voltage at output pin increases. It is connected to the analog to digital convertor IC (ADC). The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature.

- 12. Working Principle Arduino is at the heart of the circuit as it controls all functions. LM35 is a precision integrated circuit whose output voltage is linearly proportional to Celsius (Centigrade) temperature. It is rated to operate over a -55°C to 150°C temperature range. It has +10.0mV/Celsius linear-scale factor. Temperature sensor LM35 senses the temperature and converts it into an electrical (analogue) signal, which is applied to the MCU through an analogue-to-digital converter (ADC). The analogue signal is converted into digital format by the ADC. Sensed values of the temperature and speed of the fan are displayed on the LCD. Temperature and monitoring using Arduino The MCU on Arduino drives the motor driver to control fan speed.
- 13. Advantages It is an automated system . It is programmed effectively so that no interruptions would stop its functionality. To monitor the environment, that is not comfortable or possible to monitor for humans (specially for extended periods of time). Prevents waste of energy.
- 14. Due to temperature variation, after sometimes it’s efficiency may be decreased or increased. This can be improved in future design Disadvantages
- 15. Applications This project can be enhanced by using higher power electronic devices to operate high capacity DC motors. This can be used in Home Automation for controlling Fan Speed based on Room Temperature This Project can also be used in Smart Cities Public Places.
- 16. Conclusion DESIGN OF TEMPERATURE BASED FAN SPEED CONTROL and MONITORING USING ARDUINO Project was designed and Implemented. This project can be enhanced by high capacity DC motors. This project functionality can be further enhanced by using Raspberry Pi Board using 32 bit Microcontroller
