Temperature Controlled DC Fan Circuit Diagram Description: Temperature controlled Fan or Room Cooler using Arduino- In this project, you will learn how to make your own Fan, room cooler, ceiling fan or exhaust fan automatic temperature controller using Arduino, DHT11 temperature and humidity sensor, and a relay module.The Room Cooler or Fan is controlled automatically depending on the room temperature.
It is rated to operate over a -55°C to 150°C temperature range. It has +10.0mV/Celsius linear-scale factor. The 2N2222 transistor acts as a switch and controls the fan speed depending upon temperature. 1N4007 diode controls the fan from being damaged. The LED glows whenever the temperature exceeds 60°C.
Temperature Based Fan Speed Controller and Monitoring using Arduino Circuit Diagram
From smart homes to industrial processes, automation plays a pivotal role in simplifying tasks and optimizing resource utilization. One such area where automation brings immense benefits is temperature control systems. In this blog, we'll delve into the working and construction of an automatic fan controller that utilizes the UA741 IC. 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. How to Make Temperature Controlled Fan Using Arduino and DHT11: Temperature-controlled fans have become a popular DIY project for keeping your surroundings cool automatically. In this blog, we will guide you through creating a temperature-controlled fan using an Arduino board. With just a few electronic componen…
Here the Temperature controlled fan will act to the temperature changes. We have also written a blog on what temperature sensors are, if you are interested feel free to read that as well to understand more about these types of sensors. We are going to do this with a DHT11 temperature and humidity sensor. It can be done in various other ways as
Temperature Based Fan Speed Controller using Arduino 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: After connecting all the components according to the circuit diagram now our temperature based fan speed control system is ready to work. When we give the power supply to the circuit, the DHT11 temperature sensor starts sensing the surrounding temperature and generates Output values from the Data pin which gives to the Digital Pin D12 of the
