15  There are various applications for the Infra Red contactless temperature
16  sensor and MLX90632 is most suitable for consumer applications where
17  measured object temperature is in range between -20 to 200 degrees
18  Celsius with relative error of measurement below 1 degree Celsius in
19  object temperature range for industrial applications. 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.
