Accurate temperature reading of fluid near interface

A method of temperature compensation in a sensor, comprising:

• obtaining a temperature-variable property at a measurement surface;
• obtaining a first temperature at a first position within the sensor;
• obtaining a second temperature at a second position within the sensor, the second position being farther from the measurement surface than the first position;
• determining a temperature adjustment as a function of the first temperature and the second temperature;
• and
• adjusting the measured temperature-variable property based on the determined temperature adjustment,
• wherein the first position within the sensor and the second position within the sensor are separated by an intermediary material;
• wherein the intermediary material fills a space defined by a plurality of walls.

A sensor module, comprising:

• a sensor module body, including one or more walls defining an internal space;
• a window;
• an optical sensor, located within the sensor module body, the optical sensor configured to measure a temperature-variable property;
• an intermediary material, located within the internal space and in contact with the window;
• a first temperature sensor located within the intermediary material at a first position;
• a second temperature sensor located within the intermediary material at a second position, the second position being farther from the window than the first position;
• and
• a processor configured to:
• receive a first temperature from the first temperature sensor;
• receive a second temperature from the second temperature sensor;
• and
• determine a temperature adjustment as a function of the first temperature and the second temperature.
