Since it can operate and measure ambient temperature in range of -20 to 85 degrees Celsius it is suitable also for outdoor use. Be aware that electronics surrounding the sensor can increase ambient temperature. MLX90632 can be calibrated to reduce the housing effect via already existing EEPROM parameters. Since measured object emissivity effects Infra Red energy emitted, emissivity should be set before requesting the object temperature. properties: compatible: const: melexis,mlx90632 reg: maxItems: 1 description: Default is 0x3a, but can be reprogrammed. vdd-supply: description: provide VDD power to the sensor. required: - compatible - reg additionalProperties: false examples: - | i2c { #address-cells = <1>; #size-cells = <0>; temp-sensor@3a { compatible = "melexis,mlx90632"; reg = <0x3a>; vdd-supply = <&ldo4_reg>; }; }; ...
