Rust MLX90614/MLX90615 Non-contact Infrared Thermometer Driver

crates.io Docs Minimum Supported Rust Version Build Status Coverage Status

This is a platform agnostic Rust driver for the MLX90614/MLX90615 infrared thermometers using the embedded-hal traits.

This driver allows you to:

  • Read the last object temperature measurement. See: object1_temperature().
  • Read the last ambient temperature measurement. See: ambient_temperature().
  • Read the last raw IR measurement. See: raw_ir_channel1().
  • Get/Set the emissivity. See: set_emissivity().
  • Get the device ID. See: device_id().
  • Set the device address. See: set_address().
  • Put the device to sleep. See: sleep().
  • Wake the device from sleep. See: wake_mlx90614().

The MLX90614/MLX90615 are a infrared thermometers for non-contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASSP are integrated in the same TO-39/TO-46 can. Thanks to its low noise amplifier, 17-bit/16-bit ADC and powerful DSP unit, a high accuracy and resolution of the thermometer is achieved.

Depending on the MLX90614 model they feature a single-zone or dual-zone thermopile.

The chips feature an 10-bit PWM and SMBus interface.

The readout resolution is 0.01°C (MLX90614) / 0.02°C (MLX90615).

This driver uses the SMBus interface.

Usage

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

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

use linux_embedded_hal::I2cdev;
use mlx9061x::{Mlx9061x, SlaveAddr};

fn main() {
    let dev = I2cdev::new("/dev/i2c-1").unwrap();
    let addr = SlaveAddr::default();
    let mut sensor = Mlx9061x::new_mlx90614(dev, addr, 5).unwrap();
    loop {
        let obj_temp = sensor.object1_temperature().unwrap();
        println!("Object temperature: {:.2}ºC", obj_temp);
    }
}
