arduino-NextPM

arduino-NextPM is a simple library that permits to control Next-PM sensor from an Arduino (UNO or MEGA).

Next-PM sensors documentation

Information about the Next-PM sensor is available on the constructor website

Importante feature of the library

Function	Description
read_10sec(PM_DATA & data)	Measure average consentration ot the last 10 secondes
read_1min(PM_DATA & data)	Measure average consentration ot the last minute
read_5min(PM_DATA & data)	Measure average consentration ot the last 5 minutes
void configure()	Initialise the sensor
powerOn()	Startup the sensor
shutdown()	Shutdown the sensor
cleanSensor()	Clean fan of the sensor

//store data at each measure

  //open stream to print data on console
  Serial.begin(9600);
