    1 * Melexis MLX90632 contactless Infra Red temperature sensor
    2 
    3 Link to datasheet: https://www.melexis.com/en/documents/documentation/datasheets/datasheet-mlx90632
    4 
    5 There are various applications for the Infra Red contactless temperature sensor
    6 and MLX90632 is most suitable for consumer applications where measured object
    7 temperature is in range between -20 to 200 degrees Celsius with relative error
    8 of measurement below 1 degree Celsius in object temperature range for
    9 industrial applications. Since it can operate and measure ambient temperature
   10 in range of -20 to 85 degrees Celsius it is suitable also for outdoor use.
   11 
   12 Be aware that electronics surrounding the sensor can increase ambient
   13 temperature. MLX90632 can be calibrated to reduce the housing effect via
   14 already existing EEPROM parameters.
   15 
   16 Since measured object emissivity effects Infra Red energy emitted, emissivity
   17 should be set before requesting the object temperature.
   18 
   19 Required properties:
   20   - compatible: should be "melexis,mlx90632"
   21   - reg: the I2C address of the sensor (default 0x3a)
   22 
   23 Example:
   24 
   25 mlx90632@3a {
   26         compatible = "melexis,mlx90632";
   27         reg = <0x3a>;
   28 };
