Components to Make a Temperature Controlled Fan Arduino Usb cable LM35 temperature sensor 5V single channel Relay Jumper wires Breadboard An AC Fan LM35 Temperature Sensor Pinout The LM35 is a ...

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 ...

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 ...

Arduino Code for temperature-controlled fan First, we include the library for LCD and DHT sensor and then define pin for lcd, dht sensor and for fan. Then initialize all the things in setup loop. And ...

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 ...

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

The project mainly focuses on the temperature control smart fan that maintains the speed of smart fan as per the room temperature. The project is implemented by using Arduino Uno. Arduino Uno uses ...

Parts and tools Arduino UNO LM35 Temperature Sensor (Celsius) – datasheet Relay Module ( May refer to my previous post on how to make a relay module) A 9V battery (To supply to the coil of relay and ...
