Dust Sensor Mode Setting

The Dust Sensor works fine with the example provided.

However, the wiki page is mhmm about how to use the SET mode setting pin.

- Could you please elaborate about the SET mode setting pin?

The PM2.5 sensor adapter board provide two pins for a jumper. I'd like to put the sensor to sleep and thus low power mode and wake-up only before I perform a reading.
- Is there a way to drive the SET pin with a GPIO from the MCU?
Similarly, I couldn't find the schematics of the PM2.5 sensor adapter board.
- Are the schematics of the PM2.5 sensor adapter board available, and where?
Thank you!

I was able to figure out how to control the SET/SLEEP pin with an ElectricImp.

Could you please provide the picture with a higher definition or even better, as a PDF? Thank you! Rei Vilo

2. please check the attachment about the schematic. robert.chen
