You'd just have to do some modification to make it work with the common case fans you'd be using with a Morpheus II. It should be pretty easy to figure out the wiring arrangement of the harness to be able to make it work with any two 12V fans though, if you have the fans and the harness to disassemble and look at(or possibly just from the pics you can find). Which means you can't connect to it with that adapter you have. And the fan that connects to the harness with the 5-pin connector isn't wired to the 5th pin(it doesn't look like there's even a pin in the 5th hole). Since it looks like all three fans are 4-wire 12V fans(same part numbers even). I don't quite get why one of the fans is connected with the 5-pin connector. Or, rather, that it has two 4-pin fan connectors, and one 5-pin fan connector. Which in turn connects to two 4-pin fans, and one 5-pin fan. (microsec.It looks like the 6-pin connector is for(what we call in automotive terms) a wiring harness. I am not sure whether it is OK with other values.ĭouble frequency = 1000000/pulseDuration

The system operates unstable without a 560R resistor.

I can not achieve the maximum fan speed.

The NodeMCU and the fan must have a common GND.

Materials used: Prices are approximate and by memory. It took me a long time to make it work and and also a long time to make it work hard. The biggest problem is the management of the PWM FAN. I am also waiting for a Dust Sensor PPD42NJ to see if there is a result of everything I did. I also added a temperature sensor, as there were free pins on the board. My idea was to make an hourly schedule, when to blow strong and weak. I decided to do a control with NodeMCU - Arduino. I decided to buy a filter, not to make a filter (maybe I will make a filter in the next version). I looked at several projects until I make my idea. This is a single-fan filter, in the stores the prices of these devices are very high. The project is a basic idea, what can be done with hand tools and as cheap as possible.
