Getting to know the user interface

The user interface consists of three pages: 1) the Homepage, 2) the Sensor Data page and 3) the Help page.

Due to the modular design, sensor configuration is optional. Corresponding indices and sensor data are displayed only in the corresponding configuration. If the corresponding sensor is not configured, the index and data are hidden or grayed out. For more details, please check Sensor Configurations.

The following is a description of all environment/comfort indices and error messages:

IEQI is evaluated by the following separate indices.

The range of IEQI is 0 – 100, with 0 being the worst and 100 being the best:

• 90 ~ 100: very good / very comfortable
• 66 ~ 90: good / comfortable
• 33 ~ 66: bad / uncomfortable
• 0 ~ 33: extremely bad / extremely uncomfortable

Dino can gain more experience points in a better environment with higher IEQI!

Based on Fanger’s PMV model (ISO 7730).

Range: 0 – 3, with 0 being worst and 3 being best. Results in the range from -3 to +3 of PMV model were taken as absolute values.

Based on CEN/EN 16798-1 (german version DIN EN 16798-1) and WHO-ITU standard.

Range: 0 – 3, with 0 being worst and 3 being best.

Based on CEN/EN 16798-1 (german version DIN EN 16798-1).

Range: 0 – 3, with 0 being worst and 3 being best.

Based on EPA-454/B-06-001 guideline and CEN/EN 16798-1 (german version DIN EN 16798-1) standard.

Range: 0 – 3, with 0 being worst and 3 being best.

Note: when using CO₂ sensors only, even if CO₂ concentration is at a low level (e.g. < 1000 ppm), it does not fully imply that the air quality is necessarily good. CO₂ is only used as an indirect index to reflect the ventilation situation. When using multiple gas sensors at the same time, such as CO₂ and VOC sensors, the IAQI is the average of the respective indices.

For reference only.

Range: 0 – 3, with 0 being worst and 3 being best.

Note: there is still controversy about the effect of barometric pressure on comfort etc.

The electrical power measured by the power sensor with the unit Watt.

Note: This power is not the electrical power of the Ressourcenwächter itself, but the electrical power of the device/line measured by the power sensor. The default voltage is 230 volts.

RTC module not found, or initialization failed. Please check your hardware!

The possible reasons are as follows:

1. Bad connection between RTC module and Microcontroller.
2. RTC module battery needs to be replaced.
3. RTC module is damaged.

SD card not found, or initialization failed. Please check your hardware!

The possible reasons are as follows:

1. The SD card is not formatted correctly, which may be caused by a power failure while writing data. When this occurs, connect the SD card to your computer, back up all data in it, and reformat the SD card. For a detailed guide, please see: Formatting the SD card.
2. Bad connection between SD card module and microcontroller.
3. SD card type is not supported. Only FAT16/32 file systems on standard SD cards and SDHC cards with capacities up to 32GB are supported.
4. SD card is damaged.
5. SD card module is damaged.
