For those “Home Brew”, DIY pool automation types that are using Raspberry Pi micro-computers in their Swimming Pool Outdoor Control Panels (OCP) or in Swimming Pool Automation Enclosures or you are planning to in the future.

The following brand-new information may be of some use if Raspberry Pi cooling fans are of any interest or importance to you.2021-01-05_19-30-21.jpg

Looks like Sequent Micro-Systems is introducing a “smart” fan hat for the Raspberry Pi’s.
Definitely looks like it has some nice features.

Its own tiny 32-bit processor receives commands from Raspberry Pi through the I2C interface. A step-up power supply converts the 5 Volts provided by Raspberry Pi to 12 Volts, ensuring precise speed control. Using pulse width modulation, it powers the fan just enough to maintain a constant temperature of the Raspberry Pi processor.

More than one smart fan can be used within an automation stack.

The Smart Fan has its own command system, which can be downloaded from GitHub. You can control it from any program using the built-in command line system or from a Python script. A Node Red interface lets you set the processor temperature from the browser. The Smart Fan will implement a PID loop and adjust the fan's speed to keep the processor temperature you specified.

Allen,
Not at the moment. For a couple of reasons.
1. I already have the following dual-fan hat in operation. Yea, it's a "dumb" fan (running 24x7) but to replace it, I need to disconnect and disassemble the sensor/relay stack and perform a remove/replace. It's winter so just not high up on the priority list at the moment with all my other automation projects in full swing. Just thought I would share my discovery in the meantime, in case someone is looking to embark on a similar adventure.

2. I've since learned from one of the other guys, that there are some comparable fans out there and one which may even be better such as the one below.
Thanks and take care...

Does anyone have experience with this site? Prices are good, but curious about shipping times, etc.
