SDS011

Arduino library for dust Sensor SDS011 (Nova Fitness Co.,Ltd)
This library uses SoftSerial or HardwareSerial to connect to the SDS011.

Usage

• Define SDS object: i.e. SDS011 mySDS;

• Start object: void begin(pinRX,pinTX); i.e. mySDS.begin(pinRX,pinTX);

• Read values: int read(float *p25, float *p10); i.e. error = mySDS(&pm25,&pm10);

Reads the PM2.5 and PM10 values, return code is 0, if new values were read, and 1 if there were no new values.

• Sleep Mode: mySDS.sleep();

• Wakeup Mode: mySDS.wakeup();

During sleep mode, the fan & Laser stops working and the current draw is < 4 mA. The minimal run time of this sensor is 30 seconds.

Alternative with HardwareSerial

• SDS object can also be initialized with a Serial object as parameter
  i.e.

SDS011 mySDS;
mySDS.begin(Serial1);

HardwareSerial objects need to be defined if using ESP32
