Example for Using GPIO GCC Libraries on a Pi for Temp/Humidity Sensor Data #piday #raspberrypi @Raspberry_Pi

Check out this nice example of using the GPIO gcc libraries on a Pi (for those of us who want a break from writing Python code) from John.Geek.NZ who has been exploring this and other Raspberry Pi subjects for a couple of months:

After a few comments regarding my code to read data from a Sensirion SHT1x with a Raspberry Pi, I’ve got some updated code.

Please see my previous post for general information, but use the code here.

The list of changes are:

  • Added Dewpoint calculation from Page 9 of Datasheet
  • Updated Humidity calculation Coefficients to recommended (12 bit) figures from Page 8 of Datasheet
  • Updated Temperature calculation Coefficients to recommended (3.3 Volt Interpolated) figures from Page 9 of Datasheet.

If you want to read humidity sensor data into your Pi – check out our tutorial and compatible sensors!
