Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

By integrating an Arduino Uno microcontroller, a DHT11 temperature and humidity sensor, and PWM (Pulse Width Modulation), the system dynamically adjusts fan speed and provides real-time feedback ...

This project implements a temperature-based fan speed controller using an Arduino Uno. The system adjusts the fan speed based on the ambient temperature, providing efficient cooling and energy ...

This project offers a stand-alone, automated fan speed controller that intelligently adjusts the fan speed in response to temperature changes. Using embedded technology, this closed-loop system offers ...

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 ...

Continuous monitoring of the speed of fans in terms of rotations per minute (RPM) can offer several benefits such as fault diagnostics, the prognostics, and the amount of offered propulsion.
