# SDS011 library selectable serialport
|
|
|
|
Arduino library for dust Sensor SDS011 (Nova Fitness Co.,Ltd) which allows to choose the serial port used to communicate with the sensor.
|
|
Based on the work of [ricky-z](https://github.com/ricki-z/SDS011)
|
|
|
|
## Usage
|
|
|
|
* Define SDS object:
|
|
```
|
|
SDS011(Stream& serial);
|
|
```
|
|
i.e. SDS011 mySDS(Serial1);
|
|
|
|
* Start serial communication:
|
|
```
|
|
Serial1.begin(9600);
|
|
```
|
|
|
|
* 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.
