MLX90614 non-contact thermometer

The mlx90614 sensor platform allows you to use your Melexis MLX90614 non-contact infrared thermometer (Datasheet, Product Page_) with ESPHome. Sensor measures both ambient and object temperature that can be enabled independently.

The I²C Bus is required to be set up in your configuration for this sensor to work.

# Example configuration entry
sensor:
  - platform: mlx90614
    ambient:
      name: Ambient
    object:
      name: Object

Configuration variables

• ambient (Optional): Enables sensor entity for ambient temperature reading.

  • All options from Sensor.

• object (Optional): Enables sensor entity for object temperature reading.

  • emissivity (Optional): Emissivity coefficient is the measure of an object’s ability to emit infrared energy compared to a theoretical perfect black body emitter. See Emissivity Application note for details on determining custom emissivity. Default is 1.0 which is 100% and corresponds to the ideal black body.

  • All options from Sensor.

• All other options for I²C devices described at I²C Bus.
