Insights

Released as part of the Mindstorms NXT line and now retired, NXT Temperature Sensor is an education-channel accessory whose sealed scarcity gives some support, and demand is concentrated among NXT collectors while broader interest is limited by ecosystem obsolescence and modest post-retirement momentum.

Set Facts

It can measure temperatures in both Celsius (-20°C to +120°C) and Fahrenheit (-4°F to +248°F).
The sensor can be calibrated for accurate readings using the NXT software.
