What's new?

This update brings many improvements in data accuracy and connection stability as well as the files required to print the 3D case yourself!

  • STL Files for 3D Printing the case
  • Sensor data is now read 10 times before sending to the cloud and only average data is sent to the cloud.
  • No matter the reporting interval set, data from all sensors will be sampled 10 times before publishing.
    • Averaging dynamically adjusts based on the user-configurable reporting period.
  • Fixed erratical readings with PMS7003 that some users had (independent from the new averaging system).
  • Minimum reporting period is now 5 minutes.
    • If set to 5 minutes, the air quality sensor does not sleep at all. This reduces its lifespan but may be useful if short periods between readings are necessary.
    • Setting the reporting period to 6 minutes or higher enables air quality sensors' sleep.
  • Textual pollution reference values now match regulations of Republic of Serbia completely.

From previous versions

  • Utilize new production AllThingsTalk SDK with much improved stability (v1.2.0)
    • Previously utilized SDK was unreleased and in beta stage.
  • Improved temperature reading precision (v1.1.6)
    • Calibration and testing done with 7 sensors (3 different models).
      • It appears that BME280 has self-heating of about 2°C in addition to 1.6-2.0°C raise in temperature when placed inside the 3D printed case.
