Since it can20 operate and measure ambient temperature in range of -20 to 85 degrees21 Celsius it is suitable also for outdoor use.22 23 Be aware that electronics surrounding the sensor can increase ambient24 temperature. MLX90632 can be calibrated to reduce the housing effect via25 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 30 https://www.melexis.com/en/documents/documentation/datasheets/datasheet-mlx9063531 32 MLX90635 is most suitable for consumer applications where33 measured object temperature is in range between -20 to 100 degrees34 Celsius with relative error of measurement 2 degree Celsius in35 object temperature range for industrial applications, while just 0.236 degree Celsius for human body measurement applications.
