This article explains how to understand the sensor data you see in the app, using a radon sensor and humidity sensor as examples. The sensors you see in your app will depend on which Wave monitor you have, but the principle is the same.
When you select a monitor in the app to view the measurement data, you will come to the overview screen for all sensors. This overview shows the most recent sensor sample taken, and therefore gives you the current evaluation of the room if your monitor is up to date.
Radon is updated hourly, and expressed as a rolling 24hr average
Temperature, humidity, VOC, CO2, and air pressure are sampled every 5 minutes
Mold risk (available for Wave Mini only) is updated hourly, and is expressed as a 48hr rolling average
If you then click on any of the individual sensor values, you will be brought to graphs for that particular sensor. You can select to view the average value and behavior of the sensor over different periods of time, such as 48hrs, 1 week, 1 month, and 1 year.
Example 1: Radon
Wave Radon logs a radon reading once every hour.
The radon measurement you see in the "app overview" screen for your monitor is always a rolling 24 hour average, that updates with each hourly measurement that is taken.
In the example below, the radon reading is 17 Bq/m3, and this means 17 Bq/m3 is the average level of radon over the past 24 hours.
If you click into "radon" - you can see further details of your averages over different periods of time. For example: 48hrs, 1 week, 1 month, etc...
This shows the radon average for the last 48hrs, and you can see the average is 11 Bq/m3:
We recommend the ideal measurement is for at least 30 days in one location, due to the nature of radon and its fluctuations. If you initially see high levels when you first set up your monitor, don't worry, the monitor is calibrating and initial readings should not be considered when it comes to taking mitigation action.
Example 2: Humidity
Humidity is measured every 5 minutes (along with temperature, VOCs, CO2 and air pressure). If you have a Wave Radon 1st generation, temperature and humidity is updated hourly.
The reading you see in your app homescreen for the monitor is the most recent measurement of relative humidity taken (not an average such as radon). In the example below, this means 30% humidity was recorded in the room within the last 5 minutes:
You can also choose to see your average humidity levels over the last 48hrs, week, etc... by continuing to the graphs for humidity in more detail.
If you want to see your measurements in more detail with timestamps, all you have to do is log in to your web dashboard or select the "View in Web Dashboard" option in the app, where you can find more detailed graphs and customize your data how you like it 😎
