Crate scd30_i2c

SCD30 trait implementing basic SCD30 I2C CO2 sensor operations

Operations taken from interface description //! IMPORTANT Current version 0.1.2 contains basics operations, some advanced ones like calibration not yet implemented Pending stuff:

• (De-)Activate Automatic Self-Calibration (ASC)
• Set Forced Recalibration
• Set Temperature Offset
• Altitude Compensation
• Soft reset

Basic Example

Obtaining measurements, co2, temperature and humidity

use scd30_i2c::scd30::Scd30;
use std::thread;
use std::time::Duration;

fn main() {
    // Open the I2C device
    let mut scd = Scd30::new().unwrap();
    let mut counter = 0;
    scd.trigger_cont_measurements();

    scd.set_measurements_interval(2);

    loop {
        match scd.get_measurements() {
            Ok((a, b, c)) => {
                println!("Co2: {} ppm Temp: {} C RH: {} %", a, b, c);
                thread::sleep(Duration::from_secs(2));
                counter += 1;
                println!("{}", counter);
            }
            Err(e) => {
                println!(
                    "Error obtaining measurements. More details: {}. Waiting 10 seconds for recovering",
                    e
                );
                thread::sleep(Duration::from_secs(10));
            }
        }
    }
}
