This paper covers the design and analysis of a temperature sensor that measures with millikelvin accuracy. The first prototype has an energy consumption of 84.64 mWs with a sampling time of 10 seconds per measurement and a component cost of less than 100 EUR. The proposed design is able to measure within 6 mK accuracy on a subset measurement range despite a simple three-point calibration. The core circuit is enhanced with two temperature sensing elements to allow for an increase in sensor sensitivity. A further approach on sensor readout is proposed and analyzed, showing good potential in combination with linearized temperature compensation for the major part of this sensors range.enhttp://rightsstatements.org/vocab/InC/1.0/temperatureoceanographythermistorwater surfacesensorTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringDesign of a highly accurate low-cost thermistor-based sensor for the measurement of water surface temperatures in maritime researchP07 - Design of a highly accurate low-cost thermistor-based sensor for the measurement of water surface temperatures in maritime researchConference Poster10.15480/882.1323810.5162/sensoren2024/p0710.15480/882.13238Conference Poster
