Temperature Controlled FanDesigning a PCB Circuit Diagram Then we will check if the temperature value is greater than 35 or not, if the temperature will be greater than 35, then the relay will be activated and the fan will start to rotate. Hardware Part First of all, make the connection of the LCD module with the Arduino as follows: This instructable will take you through the steps necessary to create your own temperature controlled fan using an old computer fan. The materials that you will need are listed below. 1 x 12VDC computer Fan ($7.00 from Amazon) 1 x 120V / 12.6 V Transformer ($5.49 from radio shack) The fan is based on Raspberry Pi 1 and 5V relay module. The system itself is broken down into 2 sub-circuits: 5V and 12V. He connects the 5V relay to Raspberry Pi 1 in order to control the higher voltage system that is connected to the fan itself. The temperature controlled feature lies in the combination of Raspberry Pi and the embedded
The fan speed is controlled by using PWM signals. And last part of the system shows humidity and temperature on LCD and Fan runs. Then we have programmed our Arduino according to the requirements. Working on this is very simple. We have generated PWM from Arduino and put it at the base terminal of the transistor. Explanation: The NPN transistor acts as a switch, allowing the Arduino to control the fan. By adjusting the potentiometer, we set the threshold temperature at which the fan will turn on. Step 3: Connect the Potentiometer. Now, let's connect the potentiometer, which will allow us to set the threshold temperature for fan control. This paper presents the designs and the simulation of a DC fan control system based on room temperature using pulse width modulation technique, humidity and temperature sensor namely DHT11 with Arduino Uno Microcontroller. The fan will be used to reduce temperature of a room at certain level. To build the fan, we will use DTH11 Humidity Sensor.
