Controlling Our Measurement Device

After adding the status LEDs and the control button we implemented the control logic:


Sensing: As soon as the GPS and sensor data of all sensors is available (in real-time) at the server-PI it saves the data in CSV files (see this post for details).

Uploading: When the messbox is in “Ready”-state, CSV files exist and the web server is responding to a ping the server-PI tries to upload the CSV files through Websocket. When the upload is successful the CSV files get deleted.
