Rust iAQ-Core Indoor Air Quality Sensor Driver

crates.io Docs Build Status Coverage Status

This is a platform agnostic Rust driver for the iAQ-Core indoor air quality sensors using the embedded-hal traits.

This driver allows you to:

<!-- TODO [Introductory blog post]() -->

The ams iAQ-core Indoor Air Quality Module is a low-cost, ultracompact solution for detecting poor air quality. It is equipped with an MOS sensor element for the detection of a broad range of reducing gases such as CO and VOCs. A change of resistance in the presence of these gases generates a signal that is translated into parts per million (ppm) CO2 equivalent or parts per billion (ppb) TVOC equivalent units.

When defined threshold limits are exceeded, the module signals the system to initiate activities such as increasing ventilation, releasing fragrance, providing a message to open a window, switching on an air cleaner, etc. When VOC levels are minimized, the module instructs the system to return to standby, thereby saving energy, lowering operating costs and maintaining a healthy environment.

In any demand-controlled ventilation/actuation environment where air quality is important, including commercial and residential facilities (offices, classrooms, kitchens, bathrooms, living and bedrooms etc.) the iAQ-core Indoor Air Quality Module performs accurately and reliably. Plus, the module’s small size opens up a wide variety of new applications where space is at a premium.

Usage

To use this driver, import this crate and an embedded_hal implementation, then instantiate the device.

Please find additional examples using hardware in this repository: driver-examples

use iaq_core::IaqCore;
use linux_embedded_hal::I2cdev;
use nb::block;

fn main() {
    let dev = I2cdev::new("/dev/i2c-1").unwrap();
    let mut sensor = IaqCore::new(dev);
    loop {
        let data = block!(sensor.data()).unwrap();
        println!("CO2: {} ppm, TVOC: {} ppb", data.co2, data.tvoc);
    }
}
