Phyphox App Can Connect with PocketLab Voyager for Interesting New Experiments and Use Cases

The public phyphox beta for connecting Bluetooth Low Energy devices to their data logging app was released this month. A collection of ten experiments, designed by PocketLab superuser Dr. Richard Born, connects PocketLab Voyager with the phyphox app for a number of exciting new use cases, including connecting two Voyagers at once and displaying both data sets simultaneously. 

What is phyphox? 

Phyphox (physical phone experiments) is an app for Android and iOS that uses the phone's built-in sensors to collect data and do interesting experiments. The public beta for their Android app allows for outside sensors like PocketLab Voyager to collect data in their app as well. 

What can I do with my PocketLab Voyager and the new phyphox beta on Android? 

Here is a current list of the experiments published on our website that use the phyphox beta along with a PocketLab Voyager. Below are a couple of example videos.
