@Charles
Thanks for the explanation I'll cross check with other Edison users but I am sure that is the reason. We have also checked the sensor HTU21DF that works properly.
Thanks again for the job

Hello,
I have the same problem with an Arduino breakout with Intel Edison. Charles observation can be the explanation because on the breakout bus 6 is only available and INTEL might have used the I2C for other purposes preventing the TH02 from working properly.
