The display unit will store your history data that is shown on the screen, however will not store it for download purposes. If the display loses power from Ac Adapter and you don't have back up batteries in it, then the history will be lost. However this package does come with an AcuLink Internet Bridge that plugs into your internet router via an Ethernet cord and gets power from an AC Adapter plugged into a wall outlet. The bridge once connected to the sensor will stream the weather data onto our website, www.acu-link.com and the AcuLink app for Android and Apple products. The website will store your data for up to one year in 12 minute intervals that you can download as a CSV file onto your computer.
The 5N1 sensor sends outdoor temperature, humidity, wind direction, wind speed and rainfall to the display and bridge. The two other tower sensors will send indoor or outdoor temperature and humidity to the bridge for online viewing/monitoring.
