Build this temperature-controlled fan using Arduino and Lm35 to control the AC fan based on the temperature of the room. The Circuit and Code to build this project is very easy.

How It Works The LM35 sensor continuously measures the ambient temperature. The Arduino reads this temperature value through its analog input. Based on predefined temperature thresholds, the Arduino ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

A temperature-controlled fan automatically adjusts its speed based on the surrounding temperature. This project uses an LM35 temperature sensor and PWM (Pulse Width Modulation) control to regulate the ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

Connections of this temperature controlled fan circuit is very simple, here a liquid crystal display is used for displaying temperature and Fan speed Status. LCD is directly connected to Arduino in ...

PWM cooling FAN controller device using an LM35 temperature sensor and an ATTiny13 microcontroller for proper thermal dissipation ...

I will start from LM35 temperature sensor, which can be used to monitor current temperature. LM35 sensor is included in Arduino Starter Kit. Let’s connect the hardware first, put the LM35 sensor on ...
