The DSM501 has no factory calibration so there is no real baseline for the readings. Both of the jumpers could be on common pins. If different pin assignments have to made, this loop will need to be changed to suit the new arrangement. I also tried to get this to be the new 'default' dust sensor on the website, but for reasons I still don't quite understand it was never accepted as such. I can confirm that the sensor does work in the sense that if I get it close to smoke or bad air it does detect with the code I have used. Vout1 (PM2.5) from sensor is connected to D2 of Arduino, Vout2 (PM10) to D3, Vcc to Arduino +5V, and GND to Arduino Gnd pin. The 1s and 0s for any character row are combined into a bitmap that will be sent to the display. This sensor has no fan so it will never be properly calibrated even if you spend hundreds of hours tuning it.
