Since it can 20 operate and measure ambient temperature in range of -20 to 85 degrees 21 Celsius it is suitable also for outdoor use. 22 23 Be aware that electronics surrounding the sensor can increase ambient 24 temperature. MLX90632 can be calibrated to reduce the housing effect via 25 already existing EEPROM parameters. 26 27 Since measured object emissivity effects Infra Red energy emitted, 28 emissivity should be set before requesting the object temperature. 29 30properties: 31 compatible: 32 const: melexis,mlx90632 33 34 reg: 35 maxItems: 1 36 description: Default is 0x3a, but can be reprogrammed. 37 38required: 39 - compatible 40 - reg 41 42additionalProperties: false 43 44examples: 45 - | 46 i2c { 47 #address-cells = <1>; 48 #size-cells = <0>; 49 50 temp-sensor@3a { 51 compatible = "melexis,mlx90632"; 52 reg = <0x3a>; 53 }; 54 }; 55... 56
