I2C T7 Temp Humidity Sensor SHT35

Via I2C and LAbview I try to read the SHT35 Sensor. communication looks okay. I can read and set registers. Turn on and of internal settings. Bus as soon I try tpo read the Temperatur and Humidity data. In total 6 byte I only get the Temperature data and the Humidity data sticks to 256 256.

What settings are wrong?

Hello,

Hello,

We started (and unfortunately never finished) testing out these sensors, they seem rather finicky. We will look into this a bit more and get back to you.

I found out the periodical

I found out the periodical mode ( 0x2130) of the SHT35 is usable when you use the fetch command (0xE000) to read the  Temp and RH value. After some experimenting Ifound the solution for the single mode. One should reduce the closckspeed of the LabJack to 100kHz. than the singel read out of the SHT35 is working fine.
