Melexis MLX90614

Overview

The Melexis MLX90614 is a digital infrared radiation sensor. It is used to measure the surface temperature when flying at low altitudes. It measures both the sensor temperature and the object (sensor) temperature.

module: ir_mlx

Hardware

The board does have a 3.3V I2C interface.

Supplier:

Future Electronics

Sparkfun

Usage

To use the infrared radiation sensor:

File: conf/airframes/myplane.xml
  <modules>
    <load name="ir_mlx.xml"/>
  </modules>

One-time-configuration

(tbd)

The I2C address is stored in internal flash memory and is usually randomly set. To set it to a useful value put the below setting only once while setting it up:


File: conf/airframes/myplane.xml
    <load name="ir_mlx.xml">
      <define name="IR_MLX_ONE_TIME CONFIG" value="1"/>
    </load>

NOTES

If flying at higher altitudes the infrared radiation from the in-between water vapor is also measured.
