Hello everybody,
I am currently trying to read a sensor (temperature + humidity). I can read the sensor with Arduino and it already works.
Now I am trying to read the sensor with Labview over I2c. I have it connected as in the datasheet, but I get wrong values: ((
Can someone help me please?
Here is datasheet: https://sensing.honeywell.com/index.php/ci_id/142171/la_id/1/document/1/re_id/0

Solved! Go to Solution.

1. You can right click on your two indicators and choose Visible Items->Digital Display. This will eliminate the need for the extra indicators.
2. The way you are parsing the data looks almost completely wrong. Try this.

Temperature is put together incorrectly: First combine the two bytes, then shift two bits to the right. Also divide by 99.28484; the original post states incorrectly a multiplication by 100, but is has to be 165.
