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