SHT2X Library invalid value for temperature #7

Closed conrad784 closed 2 years ago

conrad784 commented 3 years ago

Hi, first of all I am loving your project, I did not succeed that my own firmware was able to talk to TTN v3 until now...

Using your software was successful, but exhibited some other quirks. I am using a Cubecell Dev Board. Connecting a Si7021 (SHT21 + HTU21) results in the right humidity signal but in -237° (in ttn then 6281). In contrast to a BMP280 (which I had lying around) which only shows invalid values right after the start, the temperature value of the Si7021 stays like this forever (multiple days). Using the sensor with the Adafruit_Si7021.h library on other boards did result in correct values.

Btw, are you planning in releasing the source code for the Cubecell Boards?

Just download the source code and try an other library for the SHT20
