Fan Controller with Feedback from Temperature Sensors
This helpful system reduces a computer’s fan speed and prevents it from overheating, thus adding a new level of safety for people who modify their computers at home. The HD64F3664BP microcontroller-based fan controller is particularly useful because it can be modified to suit a specific task. Each temperature sensor, relay, and fan output can be configured separately. The temperature is thoroughly measured by gathering data from eight different points using temperature-to-voltage converters. Plus, each of the five digitally controlled fan outputs can handle currents up to 1 A at 12 V. Programming is straightforward thanks to the user-friendly interface.
