The more blades of the cooling fan, the better the cooling effect?
Jun 13 , 2024
Then the previous article continues to say that the number of fan blades on the effect of heat dissipation factors 4. Speed and efficiency Speed: More blades may require higher speed to provide adequate air flow, which may increase power consumption and wear. Efficiency: An efficient design can provide good heat dissipation with low power consumption and noise levels. 5. Application ...

What kind of design cooling fan can read the tach signal through GPIO?
Jun 17 , 2024
Typically, the cooling fan is connected to the system through a three-wire interface, which includes a power cable, a ground cable, and a Tach cable (speed signal cable). In order to be able to read Tach signals through GPIO, you need to select a fan that supports this feature. Such fans are often referred to as "ach-enabled" (supporting Tach) or "RPM-sensing" (supporting speed detection) fans. Th...

How does GPIO read the fan tach signal?
Jun 20 , 2024
Follow up the previous blog to discuss how GPIO reads the fan tach signal 4, configure the GPIO pin as the input mode to prepare to read Tach signals. This can be achieved by using appropriate programming languages and libraries. For example, you can use the RPi.GPIO library for Raspberry PI. 5. Read the status of GPIO pin to obtain Tach signal. Depending on the programming language and lib...
