SHTxx humidity sensor.

This reads the values for humidity and temperature from the SHTxx sensor through bit banging.

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

2  <define name="SHT_DAT_GPIO" value="port,pin" />
3  <define name="SHT_SCK_GPIO" value="port,pin" />
4  <define name="SHT_SDLOG" value="TRUE|FALSE" />
5 </module>

Module configuration options

Define Options

  • name: SHT_DAT_GPIO value: port,pin
    Description: data GPIO (e.g.: GPIOA,GPIO8)
  • name: SHT_SCK_GPIO value: port,pin
    Description: clock GPIO (e.g.: GPIOA,GPIO9)

    Description: start logging to SD card

Module functions

Init Functions

These initialization functions are called once on startup.

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

  • humid_sht_periodic()
    • Frequency in Hz: 4.
    • Autorun: LOCK
      Periodic function automatically starts after init and can't be stopped.
