Struct sds011::SDS011

pub struct SDS011 { /* fields omitted */ }

Struct holds a link to a sensor and provides functions to interact with it

Example:

use sds011::{SDS011};
use std::thread::sleep;
use std::time::{Duration};

match SDS011::new(port) {
    Ok(mut sensor) => {
        sensor.set_work_period(work_period).unwrap();

        loop {
            if let Some(m) = sensor.query() {
                println!("{:?}", m);
            }

            sleep(Duration::from_secs(5u64 * 60));
        }
    },
    Err(e) => println!("{:?}", e.description),
};

Implementations

impl SDS011

pub fn new(port: &str) -> Result<SDS011>

Creates new instance of SDS011 port is required, for example /dev/ttyUSB0

Example

let mut sensor = SDS011::new("/dev/ttyUSB0").unwrap();

pub fn set_report_mode(&mut self) -> Result<()>

Sets report mode TODO at the moment sets WRITE and PASSIVE mode only

pub fn query(&mut self) -> Result<Message>

Reads data from the sensor and returns as Message

pub fn cmd_begin(&self) -> Vec<u8>

Returns command header and command ID bytes

pub fn set_work_period(&mut self, work_time: u8) -> Result<()>

Sets working period work_time must be between 0 and 30
