Lego-NXT 9749 Temperature Sensor with BrickPi

Is the Lego-NXT 9749 Temperature Sensor compatible with the BrickPi?

I tried using the given python code for a temperature sensor (using it as a raw sensor for analog) in the python project examples (Twitter or the ThingSpeak projects) but it kept giving me a temperature around -51 or -31.

This sensor is not supported; is it still sold by LEGO?

These two temperature sensors are currently supported:

The first one is the one used in the project you’re referring to. I hope this helps!
