Temperature Based Fan Speed Controller Using Arduino

Pwm is a technique by using which we can control voltage.

Temperature based fan speed controller using arduino.

When the temperature reaches the value set in tempmax the fan will be at its maximum spinning velocity and the lcd will display fans. 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. 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. In this post we have described how to design temperature based fan speed control monitoring with arduino and lm35 temperature sensor.

Temperature based fan speed control and monitoring using arduino circuit and working. The temperature sensor lm35 senses the temperature and converts it into an electrical signal which is. It is accomplished by the data communications between arduino lcd dht11 sensor module and dc fan that is controlled by using pwm. 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.

Circuit diagram of the temperature fan speed control and monitoring is shown in fig. The arduino throttles the fans using pid logic and drives them through pwm. A single side pcb for the temperature based fan speed control and monitoring circuit. The temperature based fan speed control system can be done by using an electronic circuit using an arduino board.

The temperature and fan speed are reported through a 8 digit 7 segment display fitted on a rack mounted aluminium bar. The system uses a temperature sensor to control four fans that are driven by an arduino controller. Sensed temperature in celsius scale and fan speed in percentage are simultaneously displayed on the lcd panel. Temperature based fan speed control.

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. 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.
