Thermometer in EV3

I am trying to make a simple program in EV3 that displays the tempurature of the thermometer. I cannot find the thermometer brick and found the dTIR brick. I do not know if this is the right one.

I used this brick and when I ran the programme, I am getting the value -273.16 and -661.24 switching back and forth. I know my house is not that cold. Please respond about why this is not working.
Thank you

Hey cweb,
The Dexter Industries thermometer is not compatible with EV3. Unfortunately LEGO changed some of the hardware configurations on the newest hardware without consulting us.

The Thermal Infrared sensor is indeed EV3 compatible.

Compatibility of our sensors is on the front page of our website here:

Thank you
