In climate and oceanographic research, precise temperature measurements within the very limited temperature range of the ocean are essential. 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.
