This should be the first project on YouTube that is based on the new NXT Temperature Sensor (9749).

The reading range of this “giant” thermometer was intentionally limited from -15 to 60oC to facilitate the design of this construction. However, the actual reading range of the digital NXT Temperature Sensor is much wider (from -20 to 120oC or from -4 to 248oF). Reading resolution is one decimal point (e.g. 24.4 degrees).

The new Temperature Sensor has a long metal tip (about 64mm). The total sensor tip length, including the plastic “nose”, is about 77mm. The difference with the rest common sensors (such as lignt, US, sound etc.) is that cabling is fixed, meaning that there is no connector socket at the back of the sensor. Cable length is about 51cm.

Programmed on the new NXT-G 2.0 (with Data Logging), while the NXT Brick firmware was upgraded to V1.26 (instead of 1.05).
