Another neat feature in Ruuvi Station is ‘Graphs’, which allows you to explore the recorded sensor values in graphical form. To access this feature, tap on the graphs icon on Tag Card.
The ‘Graphs’ page shows three individual XY-axis grids: temperature, relative air humidity and air pressure.
The Y-axis shows the recorded range for each, while the X-axis shows the time of recording according to the local time zone settings on your mobile device.
When you visit the ‘Graphs’ page for the first time you will be shown a popup, which will suggest that you enable background scanning. This is highly recommended, since background scanning enables Ruuvi Station to record sensor values when the app is minimised or your mobile device screen is turned off or locked.
Ruuvi Station scans sensor values according to set intervals. ‘Graphs’ is able to show the measurement history for maximum of 24 hours at a time. The ‘Graphs’ view is reset 24 hours after the first sensor value available from the individual Tag has been recorded.
Ruuvi Station records new sensor values in two different ways:
Important notice: depending the model of your mobile device, background scanning mode can be more reliable when the phone is connected to a charger.
Explore each individual grid by using pinch-to-zoom gestures and/or scroll and move through the grid from left to right or up and down by simply positioning your finger on the place where you want to start scrolling from. You can also use double tap to zoom to any XY-axis location on the grid.
