content: So I got one.My post at twitter:https://twitter.com/blenderbuch/status/1414614797602205703?s=20USB-C but only for powerNothing 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

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

content: 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.

content: Quote from: thm_w on July 14, 2021, 09:31:51 pmYou 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=rNow, evaluating how good they are is another matter.

content: Quote from: calli on July 14, 2021, 06:06:06 pmIfit is a PM1006K, you can see the specs herehttps://pdf.directindustry.com/pdf/cubic-sensor-instrument-co-ltd/pm1006k-led-particle-sensor-module/54752-927719.htmlA 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?
