Temperature Based Fan Speed Controller Using Arduino

The temperature based fan speed control system can be done by using an electronic circuit using an arduino board.

Temperature based fan speed controller using arduino.

The temperature based fan speed control system can be done by using an electronic circuit using an arduino board. Arduino micro controller is the heart of the circuit as it controls all the functions. A single side pcb for the temperature based fan speed control and monitoring circuit. Sensed temperature in celsius scale and fan speed in percentage are simultaneously displayed on the lcd panel.

The arduino throttles the fans using pid logic and drives them through pwm. In this post we have described how to design temperature based fan speed control monitoring with arduino and lm35 temperature sensor. 100 even though the temperature might increase above tempmax. Temperature based fan speed control.

Circuit diagram of the temperature fan speed control and monitoring is shown in fig. 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. 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. The temperature sensor lm35 senses the temperature and converts it into an electrical signal which is.

Pwm is a technique by using which we can control voltage. The temperature and fan speed are reported through a 8 digit 7 segment display fitted on a rack mounted aluminium bar. It is accomplished by the data communications between arduino lcd dht11 sensor module and dc fan that is controlled by using pwm. The system uses a temperature sensor to control four fans that are driven by an arduino controller.

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. Temperature based fan speed control and monitoring using arduino circuit and working.
