In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

Traditional fans run continuously or require manual control, often leading to energy waste. This project creates a smart solution: a temperature-sensing fan controller that turns ON/OFF or adjusts ...

The Arduino reads the temperature from DHT22 and adjusts fan speed using PWM. The current temperature is shown on the LCD.

Arduinoとリレーを組み合わせて使用することで、Arduinoのデジタル出力を使って高電圧や大電流を扱う機器をコントロールできます。リレーは基本的に電気的に操作されるスイッチで、小さな電流で大きな負荷をオン・オフすることができます。これは特に家庭用電器やモーターなど、Arduinoの出力 ...

This paper presents an automated temperature monitoring and control system utilizing Arduino, designed to manage temperature-dependent operations efficiently. The system integrates an LM35 temperature ...
