TemperHum HID API and daemon for linux

This is my own implementation written in C. It's a daemon that can log results differently, has debug command line switch etc.

Reads temperature and humidity values from a TEMPerHUM HID device (1130:660c)

TEMPerHUM HID device is recognized by modern linux distributions as "Tenx Technology, Inc. Foot Pedal/Thermometer". It's a device with a Tenx HID chip which controls the onboard SHT1x temperature sensor. No /dev/ttyUSBx is created for such device.

This program uses corrections to measrements which are described in original SHT1x sensor datasheet. Supports multiple devices.

There was an eariler revision of TEMPerHUM which did not have a HID chip but was using USB-to-serial CH341 chip instead. If you have such device, use Simon Arlott's program instead: http://github.com/lp0/temperhum

Usage: temper-hum-hid [OPTIONS]...

  -h, --help                Print help and exit
  -V, --version             Print version and exit
  -v, --verbose[=filename]  Print debug messages, to standard output if no
                              filename given  (default='')
  -s, --syslog              Log debug messages to syslog  (default=off)
  -l, --log=filename        Log data to log file
  -o, --out=filename        Output results to a file instead of printing it on
                              screen, can be used for creating a status file
                              which always has latest measurments
  -r, --repeat=seconds      Constantly print results, repeat every given amount
                              of seconds, devices will be reopened every 1 hour
                              in this mode, 0 for no repeat  (default='0')
  -m, --machine             Output in machine-friendly format, which is easier
                              to be parsed by bash scripts for later use in
                              monitoring tools, 4ex. Zabbix  (default=off)
Usage example:

  temper-hum-hid --log=/var/log/temper-hum-hid.log --out=/var/log/temper-hum-hid.status --repeat=60 --machine
