4. Instructions on Usage
This section provides an instructional overview of the interactive options and features of the demonstrator, it
can be thought of as the "user guide" or "instruction manual".
4.1 Wave Awake
While the demonstrator is idle on a surface a user can wake the system by waving their hand within a few
centimeters of the face of the PCB – on doing so the system will wake and display the temperature and
humidity readings – this can be seen in Figure 8.
The screen components are labelled as follows:
1. Temperature
2. Humidity
4.1.1 Display Cycle
After approximately 3 seconds has elapsed – the display will then switch and display the air quality readings
– this can be seen in Figure 9.
The screen components are labelled as follows:
1. eCO2 (estimated CO2)
2. IAQ Index (Indoor Air Quality Index – please consult the ZMOD4410 datasheet for more information
on this metric)
3. TVOC (Total Volatile Organic Compounds – please consult the ZMOD4410 datasheet for more
information on this metric)
4. Colour Status Indicator – Green – Red (Good – Bad)
After approximately a further 3 seconds the screen will revert back to displaying temperature and humidity
readings, shown in Figure 8. This will continue to occur for 20 seconds before the system will revert back to
the low power state and the display will shut down.
4.2 Hold Awake
While the demonstrator is idle on a surface a user can wake the system by picking it up and holding the PCB
– on doing so the system will wake and display the temperature and humidity readings – this can be seen in
Figure 8.
