In this article, you are going to learn about Arduino temperature controlled fan using DHT22 sensor and relay. We will use the DHT22 sensor to get the temperature value and we will print this temperature value on the LCD. 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.

Here in this project, we’ll use an Arduino uno and LM35 temperature sensor to turn a fan on automatically when the temperature is too high.
