I have exactly the same problem like @amritz.fa and @pwatts in post 2066. The post was recently closed by admin JohnC without obvious resolution. Hence the new topic. I bought the dTIR sensor for our EV3 school project, installed the Dextor sensor blocks in Labview from GitHub, ran the test program posted by JohnC but the data output is a constant “-273.16” regardless of temperature.
Is this a faulty sensor or what is going on. Thanks.
