Followed all instructions as shown on Instructables: http://www.instructables.com/id/Sensly-Hat-for-the-Raspberry-Pi-Air-Quality-Gas-De/.
After the Raspberry Pi restarted and $ i2cdetect -y 1, no data is shown in 05 and 76 positions.
I have sent several emails to the Altitude Tech team with no response. I believe this might be a faulty sensor issue than with the code.
