Temperature Based Fan Speed Controller Using Arduino

Arduino micro controller is the heart of the circuit as it controls all the functions.

Temperature based fan speed controller using arduino.

The temperature and fan speed are reported through a 8 digit 7 segment display fitted on a rack mounted aluminium bar. 100 even though the temperature might increase above tempmax. In this arduino based project we are going to control dc fan speed according to the room temperature and show these parameter changes on a 16x2 lcd display. Now arduino board is very progressive among all electronic circuits thus we employed arduino board for fan speed control the proposed system is designed to detect the temperature of the room and send that information to the arduino board.

In this post we have described how to design temperature based fan speed control monitoring with arduino and lm35 temperature sensor. The arduino throttles the fans using pid logic and drives them through pwm. It is accomplished by the data communications between arduino lcd dht11 sensor module and dc fan that is controlled by using pwm. Pwm is a technique by using which we can control voltage.

Temperature based fan speed control and monitoring using arduino circuit and working. When the temperature reaches the value set in tempmax the fan will be at its maximum spinning velocity and the lcd will display fans. The system uses a temperature sensor to control four fans that are driven by an arduino controller. The microcontroller controls the speed of an electric fan according to the requirement allows dynamic and faster control and the lcd makes the system user friendly.

Sensed temperature in celsius scale and fan speed in percentage are simultaneously displayed on the lcd panel. The temperature based fan speed control system can be done by using an electronic circuit using an arduino board. The temperature sensor lm35 senses the temperature and converts it into an electrical signal which is. Temperature based fan speed control.

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. A single side pcb for the temperature based fan speed control and monitoring circuit.
