So I got one.

My post at twitter: https://twitter.com/blenderbuch/status/1414614797602205703?s=20

USB-C but only for power :)

Nothing at the Fan_PWM. Some Eastsoft MCU, thats one of the 3ct ones?

Can't read the exact type.

I really did expect more info, this device is not that new?!

Cheers,
Carsten

Looks like a Cubic particle sensor (Chinese) - maybe this one https://www.directindustry.com/prod/cubic-sensor-instrument-co-ltd/product-54752-2240279.html

Get it clearly identified (there are markings somewhere, like around that bar code. Find a data sheet, get the protocol (likely old-fashion serial or maybe I2C) and then the supporting cast will make more sense. That's what I think anyways.

Hope it helps

All that for $12? that is incredible.
Its hard to just find a laser PM sensor alone for $12.

But yeah if you can get the serial data output (most of these use normal serial protocol), then it would be much more useful, get it displayed on a small LCD. You can scope whatever the onboard micro is doing if a request packet is needed.

You can get older ones fairly cheaply - e.g., http://www.diymore.cc/collections/new-product/products/dsm501a-dust-sensor-pm2-5-detection-dector-allergic-smoke-particles-sensor-module-for-air-cleaner-air-condition-for-arduino?_pos=1&_sid=bd444598f&_ss=r

Now, evaluating how good they are is another matter.

If it is a PM1006K, you can see the specs here https://pdf.directindustry.com/pdf/cubic-sensor-instrument-co-ltd/pm1006k-led-particle-sensor-module/54752-927719.html

A 5V device and straight no-frills serial except that TX and PWM are shared. I would need to read for a while to understand that completely - I guess you just abandon the PWM for the short amount of time that it takes to send a read request and then go back to whatever duty cycle you are using?. Are you certain that yours has a fan that you can see or hear?
