The temperature/humidity sensors of the STS3x/SHT3x family are calibrated and factory-programmed with a unique serial number. For some sensors, this serial number can be used to obtain a calibration certificate via an API provided by the manufacturer (Sensirion). Expose the serial number via debugfs. Changelog ========= v2 -> v3: - Remove #ifdef for debugfs - Add debugfs cleanup - Do not expose serial number if read fails v1 -> v2: - Change from sysfs to debugfs - Add documentation improvements Stefan Gloor (1): hwmon: (sht3x) read out sensor serial number Documentation/hwmon/sht3x.rst | 11 +++++++ drivers/hwmon/sht3x.c | 56 ++++++++++++++++++++++++++++++++++- 2 files changed, 66 insertions(+), 1 deletion(-) -- 2.41.0
