0015 There are various applications for the Infra Red contactless temperature
0016 sensor and MLX90632 is most suitable for consumer applications where
0017 measured object temperature is in range between -20 to 200 degrees
0018 Celsius with relative error of measurement below 1 degree Celsius in
0019 object temperature range for industrial applications. Since it can
0020 operate and measure ambient temperature in range of -20 to 85 degrees
0021 Celsius it is suitable also for outdoor use.
0022
0023 Be aware that electronics surrounding the sensor can increase ambient
0024 temperature. MLX90632 can be calibrated to reduce the housing effect via
0025 already existing EEPROM parameters.
0026
0027 Since measured object emissivity effects Infra Red energy emitted,
0028 emissivity should be set before requesting the object temperature.
