Part 2 | Long-Term Monitoring Needs and Product Experience (Q8–Q14)

Page 2 of 3

Q8. If more frequent data transmission or updates may reduce battery life, which update method best matches your needs? *

Update every 30 minutes – prioritize timely data
Update every hour – balance timeliness and battery life
Update every 2–3 hours – prioritize long battery life
Use low-frequency updates normally, but automatically increase the update frequency and send an alert when an abnormality is detected
As long as the device operates reliably over the long term, I have no strong preference

Note: This question asks about the frequency at which the mobile app or display receives new data. It does not represent the device’s internal measurement frequency.

Q9. How necessary is a small on-device display area for you? *

Very necessary – I want to view data directly without using my phone
Somewhat necessary – I would use it while maintaining or checking the water
It would be helpful, but I could use the device without it
Not necessary – I would view data through the mobile app
Not sure

We are planning a long-term pool water monitoring device. The device will continuously monitor free chlorine and other core water-quality parameters, with free chlorine measured directly by the device.

Q10. For this type of long-term monitoring device, which user experiences matter most to you? *

View a clear free-chlorine value at any time
View free-chlorine changes over a day or a longer period
Receive timely alerts when water quality is abnormal
Review historical water-quality data
Receive clear action recommendations in the mobile app
Reduce the number of manual tests

Multiple choice – select up to 3

In the following questions, “on-device display area” means a small screen or data display built into the pool water monitoring device itself. It does not refer to a separate indoor display or poolside display.
