6. Maintenance

As with any optical sensor, it is important to keep the lens and view clean.

Otherwise the sensor will be measuring the temperature of the obstruction

instead of the surface of interest.

Clean the lens gently with a moistened cotton swab. Distilled water or alcohol

works well for most dust/dirt. Salt deposits dissolve better in a weak acid

solution (~0.1 molar).
