In this Arduino based project, we are going to build a temperature-controlled fan using Arduino. With this circuit, we will be able to adjust the fan speed in our home or office according to the room temperature and also show the temperature and fan speed changes on a 16×2 LCD display. To do this we will be using an Arduino Board, LCD, DHT11 sensor Module, and DC fan that is controlled by using PWM.
This project consists of three sections. One senses the temperature by using humidity and temperature sensor namely DHT11. The second section reads the dht11 sensor module’s output and extracts temperature value into a suitable number in Celsius scale and control the fan speed by using PWM. And last part of system shows humidity and temperature on LCD and Fan driver.
Project customization is also available.
